3 liters of water (mineral water is better)

How to make a tofu box

Old tofu?

take 5 grams of soybeans, wash them, add 3 times of water to soak them, soak them for 8-1 hours in summer, and extend them to 9-13 hours in winter.

Take 9 grams of bittern (magnesium chloride) and add 4 grams of water to melt for later use.

Grind the soaked soybeans in batches. I use the usual machine for beating soybean milk. The ratio of soybean to water is 1:3. Filter the soybean milk with gauze, usually you will get gauze when you buy tofu boxes.

Put the filtered raw soybean milk into a pot and boil it over high fire. I will cook it twice. Because there is no big container, I should pay special attention to the boiling point, because the soybean milk will foam a lot after boiling, and it will overflow very high. Stir it with a spoon and turn to low heat for 3-4 minutes.

order tofu, which is the most critical step. Pour the cooked soybean milk into the corresponding container. When the temperature drops to about 85 degrees, spoon the bittern into the soybean milk slowly, and stir it slowly while stirring, so that the bittern and soybean milk can slowly react and solidify. At this time, when you see the small bean curd, the speed of stirring will be slowed down, and the speed of adding salt brine will also be slowed down accordingly, until the bean curd water turns blue-yellow, and after the bean curd is precipitated, it belongs to the bean curd state. Cover the pot and wait for 15 minutes. See the figure below.

scoop out a little tofu soaked in tofu gauze (see the picture below). Cover the pot and wait for 15 minutes

Soak the tofu gauze with tofu, so that the tofu will not stick to the cloth easily.

pour the tofu flower into the mold for making tofu, fold the tofu gauze and cover it with a cover plate, and press a heavy object on the cover plate. I will press it with a 4 kg water bottle for about 8 minutes, and open the tofu gauze to make fresh, tender, healthy and delicious old tofu. Note that the tenderness of tofu depends on the weight and time of pressing.
