Method of making soybean dregs into lumps: soak soybeans in water one day in advance, prepare ingredients and tools: soybeans, white vinegar, brine (bought by Taobao), molds, gauze, prepare machines, and start grinding soybean milk (preferably a soymilk machine, which is convenient and simple). It's just as good to use a juicer to make steel by indigenous methods! Mix 750g soybean with 3750ml water, and the ratio of soybean to water is 1:5. The following methods have been weighed separately: find a basin, spread gauze, pour the squeezed soybean milk on the gauze to filter the residue, squeeze the soybean milk clean by hand, and keep the remaining soybean residue for making cakes and steamed bread. Take the pot, pour the filtered soybean milk into the pot, and cook it on low heat, that is, cook the soybean milk three times. During the period, it must be stirred from time to time to prevent the pot from being burnt; Pick out the cooked bean skin (dried to make yuba), turn off the fire after cooking, and when the temperature drops to 80 -90 degrees, add brine and white vinegar respectively (preferably with a thermometer, or wait for about 5-8 minutes), and the ratio of brine to soybeans is1:50,750g of soy sauce15g of brine. This can be made into blocks.
