Soy milk: 150g of soybeans, 1050ml of water.
Tofu brain: 1.2L of soy milk, 3 grams of gluconolactone, about 20ml of warm boiled water.
You may be unfamiliar with gluconolactone, which is a white powdered crystal that is quite readily available online. It is different from the southern tofu made with gypsum and the northern tofu with brine, and the tofu made with gluconate-δ-lactone can reduce protein loss, and the finished product is fragrant and delicious, and the amount of tofu made is more than the conventional method.
Its principle is to use the gluconic acid in it to solidify the protein in soy milk, a bit like the principle of making cheese. And the method of using it to make bean curd is simple and has a high success rate! The gluconolactone you buy online is 3 grams per pack, so you don't need to measure it yourself.
Dissolve 3 grams of gluconolactone in about 20ml of warm boiled water. For the specific amount of water, you can refer to the instructions for the use of gluconolactone packaging bags!
[The practice of soybean milk: how to improve the pulp yield of soybeans? 】
The concentration of soy milk for tofu brain should be appropriate. It is recommended that you squeeze your own soy milk, and if you want to buy commercially available soy milk, pay attention to the ingredient list, and do not have other ingredients other than soybeans and water.
Soak 150g soybeans in water (1-2 hours in summer, cold weather can be appropriately extended), soak soybeans in advance to improve the pulp yield. Put the soybeans into the soymilk maker, add water to the 1200ml scale line, and press the start button of the soymilk maker.
After beating finely, pour it into the pot and bring it to a boil first (soy milk that can be heated automatically does not need to be cooked!). ), then strain through fine gauze. Try to squeeze out all the soy milk in the okara! Okara is also edible, so don't throw it away.
How to eat okara: You can add a variety of pasta, or scrambled eggs and scrambled tofu. The filtered soy milk is boiled again (the soy milk that can be heated automatically does not need to be boiled!). Turn to low heat and simmer for 3-5 minutes.
Note that soy milk must be boiled and cooked, otherwise it will be uncomfortable to drink. There is a lot of foam on the surface that can be removed, and the soy milk made in this ratio is about 1.2 liters, and the concentration is just right. The tofu brain is not too fine or too hard, and the tenderness is just right.
