Delicious Home-made Tofu - Creamy, Nutritious and Economical

It's actually quite easy to make tofu from soya beans, but you need to be around for certain stages! We did a bit of research and experimented for you. The result was a fresh, creamy tofu which we enjoyed even more than our favourite organic brands. The okara - nutritious left over fibre - can be used to make  bean burgers or even add to home-made bread and muffins and the whey (liquid left over from the soya curds) can be added to soups and sauces - nothing is wasted.

The coagulant - gypsum/calcium sulphate - can be bought from Oriental supermarkets or from brewing shops.

You can also make a quicker version from unsweetened, unfortified soya milk but it needs more coagulant  and doesn't produce such a firm tofu - good for scrambles, quiches or blending however.

Ingredients: 
Equipment:
large bowl plus cover (eg saucepan lid or plate)
colander
very large saucepan or two large pans
thin cotton bag or a length of cheesecloth sewn into one – very clean. 40x 50cm/16 x 18 inches
Food processor/blender and spatula
Tofu mould: a plastic tub – about 15cm wide x 20cm long x 15 cm (6inches x 8 inches x 6 inches).
Make lots of holes in the base and sides using a heated metal skewer or knitting needle.
Clean muslin or cheesecloth pieces large enough to line the tub and fold over the top
Plate or something flat that will fit over the top of the tofu
Weights: eg tins of food; large stones; a bowl filled with water;weights from weighing scales – just make sure whatever you use that it fits on top of the plate
Measuring spoons and a small bowl to mix the setting agent
Freezer-friendly plastic boxes and lids (for the okara and whey)
Food thermometer – not compulsory but it helps to get the soya milk to correct temperature - 75°C.
 
Ingredients:
450-500g dried soya beans (the pale yellow variety). Use organic if possible.
Setting agent:
  • 4 tsp calcium sulphate (gypsum) Gypsum is a powder can be bought from home-brew shops
Method: 

1. Soak soya beans for 8 hours plus (Maximum 24 hours). If the weather is warm, drain, rinse and replace with fresh water at least once. Beans ready to go are tender enough to bite through. Place 3.8L fresh water in the big pan and bring to the boil. If using two pans, just divide the water in half and do the same. The mixture will look quite smooth and foamy.

2. Meanwhile, drain half the beans and place in the food processor with just enough water to cover. Blend well – about 2-3 minutes – until the beans are very finely ground. Scrape down the sides at least once and blend again to incorporate everything into the mix. Remove from the processor, place in a bowl and repeat the process with the other half of the beans.

3. Place the bean mixture in the boiled water – the total volume should only fill half the pan. If it’s more, split between another pan. Bring to the boil, reduce to a medium heat and watch carefully. If the beans start to foam over, pour a little cold water over the top. Cook for 20 minutes. The foam will subside gradually and change into a grainy liquid – this means the milk has separated from the fibrous part of the beans.

4. Line a large bowl or another pan with the cloth bag and slowly pour the mixture into it a bit at a time. Use a strong wooden spoon or spatula to press the mixture down, so the milk goes through the bag and the fibrous part – okara – remains. Alternatively, use very thick rubber gloves to squeeze the bag by hand. Do this in stages until all the mixture has been strained. Freeze the okara in small portions – it is highly nutritious (protein, fibre, iron) and can be blended in with soups, stews and so forth.

5. Keep the soya milk hot but don’t let it boil. It should be about 75°C. Now dissolve the nigari or gypsum in a little lukewarm water. Add it to the hot milk in stages, stirring in. As soon as curds start to separate from the liquid, stop adding it (ie don’t use it all unless necessary).

6. Cover the pan with a tight-fitting lid and leave for about 15 minutes. Now stir very gently to see the state of the curds. They should be fairly big and totally separated from the yellowish liquid. If the white particles are still very small and floating all around in the liquid, add the rest of the nigari liquid if you have some left, or make up an additional teaspoonful's worth of powder and water. Stir in, and put the lid back on for an additional 10-15 minutes. Wet the cotton cloths and line them in the tofu moulds.

7. The curds should have sunk to the bottom. Sink in a sieve and use a ladle to scoop out most of the yellowish liquid - this helps to prevent damaging the curds. (The liquid can be used as stock - or freeze it.) In the saucepan, you will be left with mostly curd and a bit of liquid. Pour the curds gradually and carefully into your mould, letting the excess liquid drain out a bit each time you do so.

8. Cover the curds with the cloth then the lid then the weights. Press down gently to remove more liquid then place the tofu press over a raised area such as a draining rack or in a colander placed in a bowl so the liquid can drain freely. Leave for at least 15 minutes or longer to get a firm tofu. Then gently remove from the mould and place into a bowl.

9. Taste a tiny piece of tofu. If it tastes a little bitter from the coagulant, place a sieve over the top of the tofu and run cold water gently over it for about 20-30 minutes. Then drain and place in a plastic box. If eating on the same day, don’t bother adding water. If using in the next 2-3 days, cover it with water and a lid and store in the fridge until needed. If it doesn’t taste bitter, just store as above. Drain any water off and pat with a clean cloth or kitchen roll before cooking.
