I didn't make it n times. I made it today by mistake and it didn't smell sour at all. It solidified very well.
Step1:Soybeans must be soaked in the morning the night before. Wash the soaked soybeans again. Pour 1500g clear water into the soymilk machine and then pour the washed soybeans in. Cover the soymilk machine and plug in the power cord. Turn the soymilk machine to the juice key. Play three times.
Step2:Beat the soymilk and filter it twice. Pour the filtered soymilk into the stainless steel pot, boil it in high heat, turn it to low heat, and cook for another five or six minutes. When cooking the soymilk, don't stop using the big spoon to stir it slowly (otherwise, the bottom of the pot will be bad to drink). Put the boiled soymilk aside and leave it alone
Step3:Prepare a bowl, pour in a small half bowl of warm boiled water, and then pour in the prepared inner fat and stir it for a few times. In the past minute, a piece of soybean skin appears on the soybean milk. Use chopsticks to pick out the soybean skin. Finally, pour the beans into a clean electric rice cooker, and then pour the inner fat water into it. Use a spoon to multiply it by the soup and pour it in (just like making a cake, you can't make a circle) Remember to get the floating bubbles out. Just cover the pot and wait 20 minutes for the fragrant tofu brain (I tasted it and thought it was so delicious that it was better than the outside ones
Cooking tips:Soymilk must be cooked raw. The key is to use electric cooker to keep warm and cook delicious dishes.
