Soya - Information about Soy and Soya Products
Make tofu at homeHere we explain how to make tofu at home. Tofu is made by coagulating soymilk with salts such as calcium sulphate or magnesium chloride. In Japan they use nigari, which is basically magnesium chloride with other trace elements. We prefer to make tofu with calcium sulphate because it is the cheapest coagulant and adds extra calcium to your diet. Asian people make daily fresh tofu but in Western countries only very few people have ever tried. Home made tofu tastes very fresh and contains no preservatives. When we make tofu we also make our own soy milk, usually with a soy milk maker, such as the filterless Soyquick. The only special equipment you need is a tofu mould, which basically is a plastic or stainless steel container with holes.
IngredientsTo produce about 400 g of tofu you need 2 liter soy milk and two teaspoons natural calcium sulphate. Instead of calcium sulphate, you can also use nigari, but whichis more difficult to find. Another reason that I prefer calcium sulphate is that nigari has a slight bitter taste.
Curdling the milkBoil the soy milk for about 5 minutes and cool down to about 70-80C. If you make soy milk with an automatic soy milk maker you only have to cool down the soy mil a bit, no need to boil it again.
Dissolve two teaspoons natural calcium sulphate in one cup of warm water. Do not leave the coagulant to long in the water, otherwise it will harden. Less coagulant produces softer tofu, more produces harder tofu. Pour the prepared coagulant solution slowly into the hot soya milk, while gently stirring the soya milk and allow the mixture to stand for 15 to 20 min. If there is still some milky area after adding all coagulant solution, mix some more to use. I also tried to add the calcium sulphate powder directly to the hot soy milk and that also worked!
