Homemade tofu brain

i've been trying to be a tofu brain and i'm afraid i'm not going to succeed because i've never been able to do it because i've been able to do it because i've been able to do it a few times, when i've been shopping for esters. i accidentally saw a post on homemade tofu brain, saying that if we remember three numbers, we can do it. these figures are 100 g for dry soybeans, 900 g for water and 3g for mercuric esters. after three exercises, it worked, except for a slight change in water usage, where i used 900 ml, slightly less than 900 g water, which is exactly three grams a pack of impregnated esters, which is very convenient。
