Raw material: soybean. Practice: 1, soak soybeans, remember to pick clean, impurities and bad beans before soaking, and then wash them for about one night. This time, about 1.2 Jin of dried soybeans were soaked, and then washed for later use. 2. Beat soybean milk. Stone mills were used in the countryside before, and later grinders were used. You can only use soymilk machine instead at home. It takes about one part of beans and five parts of water. The filter screen that comes with the soymilk machine does not need to be removed. The finer you type, the better. But pay attention to the instructions of the soymilk machine. Don't burn the machine for too long, there will be many bubbles in a dozen. Soymilk machine is small and needs to be beaten many times. 3. Filter bean dregs: Put soybean milk in a common container at home, or use a pot. Spread two layers of clean gauze on it, pour the beaten pulp into the gauze and squeeze out the soybean milk by hand. 4. After squeezing, cook the soybean milk. Remember the small fire, someone must watch it, because there will be many bubbles when the soybean milk is cooked, which will easily overflow. At this time, you can simmer on a small fire and peel off the foam. After the soybean milk is boiled, it should be boiled for more than five minutes, otherwise it will smell like beans, which is to make soybean milk. Drink it while it's hot. Now it's time to order the brine, which is bought from the tofu merchant. One yuan a bottle, about 400ml. We didn't order bittern either. The point is: the temperature is 1. The temperature must be kept at about 80 degrees. 2. The amount of tofu cooked at home is too small, and it is easy to marinate slowly, otherwise it is easy to age. Add brine evenly, or tofu will be tender and old. Add brine into soybean milk, drop by drop, and gently stir in one direction with a spoon. The amount of bittern will be judged by vision. 3. Keep the temperature for half an hour after ignition to allow the precipitate to fully react. This time is the tofu flower at home. You should eat it, scoop it into a bowl, add some egg skins, shrimp skins and seasonings ... 6. Prepare a basin that can filter water, spread clean gauze, and scoop tofu flowers into the gauze. 7. Wrap the bean curd with gauze, and then press it with a heavy object to help squeeze out the water. I use a basin of water at home.
