From the Kai Lab: Ginger Beer

Ginger beer: nature's own champagne! This spicy, yet refreshing drink shares the same esteemed position in my book as properly cured bacon, Valrhona chocolate and being groped on a crowded bus. There are a gazillion recipes available, most of which are very similar. This delicious combination of ginger, lemon and sugar is easily made as you'll soon see.

You're going to need:
Bottles - plastic screw-top soft drink bottles will work very well. However, I used a dozen 330ml glass Tui stubby bottles. The size is convenient - you'll easily consume the contents and won't end up with half-consumed bottles of beer.

Bottle steriliser - obtained from your local home brew store; 250 grams cost me $6 (you're only going to use a few teaspoons of it with this batch)

Large jar and some fabric to cover it (muslin or similar - DO NOT use a jar lid or anything solid - the bug you're going to make needs to breathe)

Funnel

Large pot

To make the ginger beer bug:
1.5 teaspoons of dried yeast (I got mine from the home brew store, although you can buy the same kind from your supermarket)

2 teaspoons of ground ginger

2 teaspoons of sugar

600 ml of water (try and use spring or bore water - your town supply will have chlorine in it and while the amount is minute, it may impede the development of the bug)

To make the beer:
3.5 litres of water (see above for water)

500 grams of sugar

The juice of 2 lemons

Let's make the bug: place the yeast, ginger, sugar and water together in the jar and mix. Cover with your fabric and place somewhere warm. After twenty four hours, feed the bug a teaspoon of ground ginger and a teaspoon of sugar. Do this everyday for ten days. You should see it slowly bubbling away, the gas being carbon dioxide, a product of the yeast feeding on the sugar. Note the layer of sediment below.



On the tenth day, prepare your bottles. Clean and soak in the sterilising solution. It wouldn't hurt to put your other tools, like the funnel, into the solution too. When done, thoroughly rinse with cold water.

To make the beer, place one litre of water and the sugar into a big pot; heat gently, stirring until the sugar dissolves. Remove from the heat, add the rest of the water and the lemon juice.

This next step is a little tricky: pour off the liquid in the jar, while trying not to disturb the sediment. Strain this liquid through some cloth into the pot. Resist the urge to assist the liquid by squeezing the cloth - you want the liquid reaonably clean.

Give the liquid in the pot a quick stir. Pour the mixture into the bottles

Once poured, cap your bottles. Incidentally, I found my bottle capper for $20 on Trademe, and it came with a big bag of caps. Don't press down too hard or the bottle neck will break (I lost one on my second attempt).

Once your bottles are all securely capped, store them somewhere cool and dark (retirement home managers tend to get a bit narky if you take them there, so try somewhere else). Keep them there for a couple of weeks and for goodness sake, don't shake them.

Wondering what to do with the bug? Divide it, place the other half into another jar and continue to feed them both as before - you'll soon have twice the beer you started with! Better still, give one of them away.

Once the two weeks is up, pull the bottles out (as many as you need) and chill thoroughly - this stops the activity of the yeast in its tracks. Before you open your bottle, tip it upside down so as to allow the layer of sediment that's formed to be evenly dispersed throughout the bottle (if you're a bit squeamish about this sort of thing (*snort*), you could decant the bottle or simply filter it through a napkin as you pour it into your glass). Now open and and enjoy! It should be pointed out that it'll be quite fizzy when it's opened and will pour out of the top unbidden - it's not called nature's champagne for nothing.

So what does it taste like? Is it like a bought one? Stay tuned as my first batch (v1.0) will be sampled this coming Sunday...

Look at these rioting students rampaging through the streets of Dunedin - if only they'd had some refreshing ginger beer instead...

Fancy a little experimentation? Add honey at the beer preparation stage, preferably something mild so it won't compete with the flavour of the ginger. Also, adding a teaspoon of liquid honey with your daily dosing of sugar and ginger makes the beer taste incredibly smooth (hat tip: Kerry). With my next batch, I might try using root ginger, to see if there's a significant difference in taste.

Addendum: found a great ginger beer at my local farmers market - "Honey Buzzz - Honey 'n' Ginger Beer" one of the great products produced by Hawkes Bay microbrewer, K.E.A. Brewing ltd (Williams St, Hastings).
Also, if you're using glass bottles, make sure they don't have a thread. The bottle capper has difficulty getting a good grip because the thread is in the way. My bottles did and that was the reason why I had breakage, not to mention some difficulty making an effective seal.

Purple Carrots

The Southland Times has a story about the rise in popularity of the purple carrot (link via Stuff). Carrots once came in a wide variety of colours, but changed over time to orange thanks to the influence of patriotic Dutch growers in the sixteenth century. Did you know there's a variety named after Jimi Hendrix called "Purple Haze"?! This article explains its origins and goes into detail about carrots and their intriguing history. Who'd of thought "carrots" and "intriguing" could share space in the same sentence...

Oh, Delia!

Hello! Clearly, I haven't posted in a while. I have a big post in production but because of its outdoorsy-weather dependent nature, and the fact that the weather here has been diabolical, I've simply not been able to finish it. Fortunately, the weather is improving so it should (fingers crossed) be ready by next week.

In the mean time, here's a little clip that's been floating around YouTube for a while. It's Delia Smith, as you've never seen her before...



Waahey, Delia!

From Wikipedia:
"Delia Smith, frequently seen wearing Norwich City Football Club's team colours, has developed something of a cult status amongst football fans in the UK after a drunken half-time outburst in a Premiership game against Manchester City in front of the Sky Sports cameras at Carrow Road. Delia was shouting "Where are you? Where are you? Let's be 'aving you!" over the public address system after the Canaries had thrown away a two-goal lead before half-time. Delia, along with husband Michael Wynn-Jones... has a majority shareholding in Norwich City FC."

Apologies for the lazy post - the next one is going to be a goodie, as long as I can catch those slippery devils (hint hint)...

Muttonbirds - Titi

Have you ever wanted to try a muttonbird but were too chicken (ah, comedy gold!) to give it a whirl? Take a look at this weeks effort in the kai lab.
First, some background. Muttonbirds, known also as the Sooty Shearwater or Titi amongst Maori, are a member of the petrel family. The origin of the name refers to the mutton-like taste of the flesh, and possibly the woolly appearance of its young. It is the chick that is harvested, found in vast numbers living in the multitude of burrows on the small islands near Stewart Island (Rakiura). The season starts on the 1st of April and goes through to the 31st of May. All activity is administered by Rakiura Maori (Ngai Tahu) and their sustainable harvest programme. To that end, the bird population is monitored in conjunction with the University of Otago. The harvest is an age-old event for the islanders, being one of the few large-scale harvests of petrels in the world. Consequently, it is of immense significance, providing as it does income, an opportunity for families and those connected to meet, work and socialise together, as well as being an important facet of cultural life for Maori in the South Island.
The process: once the chicks are collected, they are plucked and then the feet and wings are cut off. They are then dipped in wax to help remove the layer of down on the bird's body. Once hardened, the wax is cracked and removed, taking the down with it. The birds are then packed in salt and placed in buckets for shipping to market on the mainland. The birds are expensive and available for a limited time. I bought mine from the Albert street market in Palmerston North; I've seen them for sale at fish markets, non-chain butcher shops and once at Pak 'n' Save in Hastings.


The bird is the size of a very small duck. It's fatty, a feature necessary for a bird soon to spend long periods of time at sea (except this one, obviously). Cooking them takes a wee bit of time. Your kitchen will also become quite pungent for a while. Personally, I don't mind the smell but some people might, so don't say I didn't warn you... I cooked mine with puha and I also made some gnocchi - more on those soon.

Find your puha, wash and put aside. Take your muttonbird and pluck off any downy feathers that may be left. Place in a pot of water - lots of water. Pop the lid on, bring to the boil and then simmer for an hour. Once the hour's up, drain off the water, and repeat the entire process. By the way, are your windows open? Go open them... Or turn your rangehood up to eleven.

Again, once that hour has been reached, drain off the water. As you can see from the photo, the bird possesses an astounding amount of fat, even after that initial change of water; the second change will take care of that though. This time, when refilling the pot with water, you'll only need enough to cover the bird.
Once the bird has simmered for about 30-40 minutes, whip up some gnocchi, dumplings or doughboys. During this time, hurl your puha into the pot with the muttonbird.
Time to cook the gnocchi. Remove the bird from the pot and keep warm - turn the heat up and drop your gnocchi into the pot to cook. While this is happening, remove the skin off the bird and don't play with the light settings on your camera, even if the results look good (deceptively so) on the camera's LCD screen...
Voila! Muttonbird, puha and misshapen gnocchi! It was very tasty - the meat of the bird is quite dark and does indeed taste like mutton. I've read grumbles about muttonbirds tasting overly greasy, salty and/or fishy - patently untrue. Changing the water minimises those potential problems, thus bringing out the flavour of the food as well as making it a bit healthier. If you make this for your family, you might want to remove the bones for your littlies. One bird would feed two people at a stretch, and given the cost (anywhere from $12 to $18 a bird), this is probably a truly seasonal treat (unless you 'know' people).

Other methods of cooking muttonbirds I've encountered involve grilling after boiling (reasonably common), boiling in milk (!) and an odd french story involving boiling in brandy (done presumably because they were French and can get away with that sort of nonsense).

Fancy something a little more flash? Try titi orzo by brilliant New Zealand chef Anne Thorpe.

Kontiki - Hawke's Bay, May '07

Last May, as Hawke's Bay's Indian summer was drawing to a close, Kerry and his son Caleb took me fishing in Napier - first to the river mouth at Haumoana to catch bait and then to Westshore to launch the kontiki.

A kontiki uses the wind to tow a longline rigged with bait out to sea. The kontiki itself takes many forms - some are small floats or rafts, propelled by kite, sails or an air sac; some (as in Kerry's case) are as simple as a weighted rubbish bag!

At days end, there was quite a respectable haul - seven Kahawai, five Gurnard, Mackerel and Red Cod - plenty of good eating to be had.

Here's a selection of photos from the big day (or click here to be taken to the set at Flickr) - please bear in mind I'm no Annie Leibovitz...

WILDFOOD #2: Wild Weeds - Nut Bars with Karengo Goodness!

Bron's theme for the second WILDFOOD event is 'Wild Weeds'. I was wandering around town, wracking my brain for an idea to submit, when suddenly I saw it before me - a kelp and nut health bar! Kelp = seaweed = wild weed! These beauties were sitting on the shelf of my local health food store, reeking of healthy, knit-your-own-muesli, sock-and-sandal goodness. I stopped and considered them for a while, thought about shoplifting them, remembered I was middle-class and then realised I might just be able to make them myself substituting the kelp with the big dried bag of karengo I have at home...

Karengo is a type of seaweed, a member of the porphyra family found on parts of the New Zealand coastline. Maori harvest it for eating - its health benefits are substantial: high in protein, selenium, iodine and a raft of other minerals and vitamins.

Powering up the laptop, I googled for a recipe and found this. It seemed simplicity itself - I had everything at home so it was off to the Kai Lab for some baking! I changed things a little using:

-1 cup of chopped macadamia nuts
-half a cup of sesame seeds
-half a cup of chopped peanuts
-handful of dried karengo fronds (you're going to end up with about 4 teaspoons worth of karengo powder)
-half a cup of maple syrup

First, into the blender went the karengo - let rip until it turns into a powdery dust (don't use a food processor - it's a little too big and the karengo will just bounce off the spinning blades).
Nuts. Hurl into the food processor with the karengo and blitz until blended. Add your maple syrup, mix thoroughly, remove and press into a greased baking pan. Bake for twenty minutes at 150 degrees celsius (preheat your oven).
Thirty minutes later (!), I sprint into the kitchen, remove the bars and after some judicious trimming of overly-brown bits, voila! A healthy wild weed-ish snack - very sweet and nutty, with just a hint of saltiness from the karengo. Nuts are a good source of protein, have a low GI and may even lower cholesterol. Karengo is unbelievably nutritious but is little known as a food source outside of the Maori community. The season for Karengo harvest in Hawke's Bay isn't too far away and I'll be doing a post on its gathering, as well as a recipe.

A big thank you to Bron for letting me play:)

Hanging out for Hangi

Putting down a hangi can be a lengthy, labour intensive business. Done properly however, it can result in the most glorious outcome (just like sex, except dirtier). Imagine then, the effort required to feed 120 people! With the apple harvest at the orchard finally winding down after two long months, a hangi was put down as a way of saying 'thank you' to the staff for all their efforts. Thanks to the expertise of John and Fish, you'll see how it all took place, step by step.

Firstly, a definition. A hangi is a traditional Maori way of cooking food, done in a pit using heated stones and/or pieces of iron, with water or leafy vegetation thrown on to to produce steam. Wire baskets of food wrapped in foil and muslin are put on top of the hot stones and iron. The baskets are covered with wet sheets and then wet sacks. All this is then covered over with soil. The water in the sheets and sacks is turned into steam by the hot stones; with the steam trapped under the sacks and soil, the food begins to cook.
A lot of preparation is required for a hangi. Before you start, you'll need to find out the fire regulations for your area, so call your local council - during the summer for instance, fire bans are often in place. When choosing a site, two key factors to consider are wind direction and the proximity of buildings and vegetation. Finding yourself engaged in battling a rampaging bushfire alongside the emergency services while caught in the full glare of the nation's media is embarrasing but can be avoided as long as you plan ahead. Finally, you'll need ready access to water, for soaking the sheets and sacks you'll need later on, as well as for controlling the fire if the need arises.

So, what to cook? Typically, you'll find pork, beef, lamb, mutton and chicken in the hangi basket. Root vegetables such as potatoes and kumara (sweet potato) as well as others like pumpkin and carrot cook well in a hangi too. Steamed puddings and stuffing are are also well suited.In the days leading up to your hangi, you'll need to hunt down some special material. Look around for some metal baskets - old deep freezer baskets stripped of their plastic are ok - these will hold the food to be placed in the pit. It also protects it from the weight of soil that'll be piled on top, as well as allowing space for steam to circulate. Keep an eye out for at least five or six hessian sacks (make sure they haven't been used to hold chemical of any description) and put aside some old cotton bedsheets. A supply of muslin or mutton cloth for wrapping the food prior to placement in the baskets is essential (oven bags work just as well but muslin allows the hangi odour to permeate the food, as well as being inexpensive). An old tub or drum is useful for soaking the sheets and sacks. Find some heavy gloves which you'll need to protect your hands from the heat while shovelling embers. A large bag of watercress or cabbage leaves for placing on the stones once hot (they'll produce steam). Finally, make sure you have a good supply of firewood (enough for a couple of hours burn time), kindling and some newspaper.

Finding stones and iron may be tricky but once found, they'll serve you well for an unbelievably long time. The best stones to use are volcanic or igneous rock which, once white hot, retain their heat for a long time. Some of this rock finds it way into rivers and is identified by its 'glow' under the light of a full moon (!). Maori Food lists the types, locations and how to gauge the suitability of stones here (scroll down to " 3. Gear Check List : Stones". The section is part of a well written page on hangi - well worth a read). Pieces of iron, such as cut-up railway track, heat up quicker than stones but the heat dissipates rather quickly too. The number of stones needed depends on the size of your pit. As a very rough guide, you'll need enough to loosely cover the bottom of the pit.Where possible, try and prepare as much as you can the day before: cutting the firewood (cover the pile if it's to be left overnight to protect it from rain or overnight dew); digging the pit (cover this as well); soaking the sacks and sheets in water; preparing the meat and vegetables (with meat, make sure it is WELL THAWED); rounding up your stones and irons, spades, rakes, shovels and a hose or large water container.
Soaking the sacks overnight in water allows them to become thoroughly saturated. This is essential because it aids in generating steam as well as keeping the steam trapped inside the pit (not to mention keeping soil off the food). Do the same with the sheets - soaking provides water for steaming the food as well as preventing burning. Have them all soaking in your tub or drum near the hangi pit.

When digging your pit, use your baskets as a guide to the size you should dig your hole (keep in mind too that you may end up stacking your baskets). Place them on the ground, mark out the area around them, and when digging, make it a little bit bigger so you can tuck the sheets down the side. The hole should be big enough for the stones and over a third of the depth of your baskets.

Having dug the pit, fill the hole with newspaper and kindling. Layer your firewood on top in a latticed pyramid formation; bear in mind that you'll need sufficient fuel for the fire to be burnt down to embers within one and a half to two hours - enough time for the stones to become white hot (red hot for iron). This level of heat is required for the stones to be able to thoroughly cook the food, thus minimising the risk of illness from bacteria. Once the firewood is stacked, place the stones and iron on top of the wood. Again, if you're doing this the day before you fire up, cover it so as to protect the pit and firewood from surprise rainfall or overnight dew.

It should be mentioned at this point that many Maori heat their stones next to the pit, not in it as shown here. The reason why John prefers lighting the fire in the pit is that heated stones placed in a warm pit retain their heat more readily: heat is not being leeched from the stones by the surrounding cold earth. The principle is similar to that of a good barista serving hot coffee in a heated cup - it stays warmer longer. However, you must be careful to remove all of the embers and ash from the pit otherwise the food will taste overly smokey.

Time to light the fire. Ignite and allow to burn until all the wood is burnt to embers and ash in the pit (again, taking one and a half to two hours). Use the shovels to reposition any rocks that fall out of the fire. The rocks should be white hot (iron, red hot). Keep a close eye on your fire and make sure you have water handy. Replenish the fire as needed, and ensure the tub of wet sacks and sheets are nearby.

While the fire is burning, organise your food. Place food into mutton cloth or oven bags and place in baskets. The order of placement is important because everything will be cooking at the same time. Place the large dense meats such as mutton and pork on the bottom, fat side down, with chicken on top of that. Place your root vegetables on next with the stuffing and steamed puddings on top. Once you've gotten word that the stones are ready, round up some helpers and bring the baskets out to the hangi pit.Once the fire has burned down, don your gloves and use the shovels and rakes to scoop out any smoking embers and ash - only the stones and iron are to be left in the pit. This is hot work. Rake the removed material away from the pit and into a pile. Dowse with water. Spread the rocks out into an even layer.Once the pit has been cleaned, throw some water (a cup or so) on the stones - this will generate steam. Sometimes too much water can be used, resulting in rapid cooling. Placing watercress or cabbage leaves on the stones minimises that risk while generating the desired effect, the moisture being released from the leaves more slowly and steadily.
Moving quickly, place the baskets on the bed of stones and iron, large items first; stack anything smaller on top of this. Get the wet sheets and lay them over the baskets, draping the sides - ensure everything is well covered.Place the wet sacks on top of the sheets. Make sure they cover the sheets, but do not allow them to go down the sides of the baskets; they must lay on the top of the ground.Start shovelling soil on top of the sacks. Any areas where steam can be seen to be escaping must be covered with more earth: escaping steam means escaping heat. Ultimately, you'll end up with a small mound.

The cooking time depends on the number and size of rocks, the amount and size of food baskets, as well as the size of the largest cuts of meat but generally speaking the cooking time will be three to four hours. It's quite difficult to overcook a Hangi as the longer it stays in the ground, the more the rocks cool. This stands in contrast to cooking in an oven where the temperature is kept at an even and constant rate.Time to uncover the food. Remove the soil from the sacks - steam rising from where you've dug is a good sign!Once uncovered, pull the sacks back off the sheets being very careful not to get dirt on them. Pull back the sheets (it will still be hot - keep those gloves handy), again being careful not to get soil on the baskets.Remove the baskets from the hangi pit and take them to the kitchen. When removing the meat, check the centre to ensure that it's cooked thoroughly. Serve and eat!The annual end of harvest hangi has been a feature of orchard life for the last three years - this was the best yet. Succulent pork (so enticing that people were snaffling samples as it came out of the pit!), moist chicken, fragrant bread stuffing, lightly smoked potatoes, sweet steamed pudding with enough cream to make a heart specialist swoon - brilliant! The evening ended with drinks, dancing (the table kind mostly) and an unscheduled bonfire. Children may have been conceived that night...


A twenty one gun salute to John, Fish, Di, Sarah, Doug and all their hangi helpers - the day was all the more special for their hard and tireless work.

And a huge thank you to Sarah, photo journalist and table dancer extraordinaire, for taking photos throughout the day (I had people to look after, pffft).
