How To Make Tofu (1)


To 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 milk

Boil 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!

Forming the tofu

Once all soya milk is separated into small white curds of tofu and an amber liquid, transfer this coagulated dispersion into a mould lined with cheese cloth. A small weight is placed on the lid of the container and allowed to sit for about 20 minutes. Empty the resulting block of tofu, which should be firm enough to hold together, into a tub of cold water, store it in the refrigerator and change soaking water daily. When you intend to eat the tofu the same day, or the day after, there is no need to store the tofu in water. To make tofu with extra texture, place it in a sealable container, cover with water and freeze. The tofu will have a more fibrous texture after thawing.
