What is the process of making tofu?

In the countryside in-laws are making their own tofu.

1, selection of fresh soybeans, dry selection method of sieve or water selection method of sieve to remove debris, poor quality beans, grass and sand and other impurities. 2, soaked soybeans soaked in water to remove impurities floating on the surface of the water, the amount of water to submerge the soybeans shall prevail. In the process of soaking, to prevent the soaking water quality becomes acidic and rancid, and affect the quality of soymilk, according to the specific circumstances of the timely change of water 1 time, soaking time varies according to different temperatures, generally 4-6 hours of soaking in the summer; winter can be extended to 9-12 hours. 3, grind the soaked beans in several times to add to the grinder, adding soybeans while adding water and grinding into soya bean paste, generally 0.5 kg of soaked beans with water 0,5 kg. About, grinding, adding beans and water to be uniform, and grinding speed coordinated, so as to grind out fine and tender soybean paste. 4, filtering soybean paste filtering generally use filter cloth or flour bag, the grinding of soybean paste 5 kg (equivalent to about 1 kg of dry soybeans) to add about 20 ℃ warm water 2

.5 kg, mixing and uniformly loaded into a cloth bag, lifting the cloth bag, shaking the bag, to be the pulp flow, repeated Operation 3-4 times, until the slurry drained until. 5, cooking pulp

Take the filtered raw soybean milk into the pot, fierce fire heating and boiling

(or steam heating) cooking to the surface of the pot of soybean milk foam rupture, remove the fire will be cooked soybean milk. 6, point pulp pointing pulp is generally used gypsum powder as a coagulant, 10 grams of dry soybean need to be equipped with gypsum about 1 kilograms.

The method of point pulp: the boiling soybean milk scooped out of the pot after a little cold, until the temperature drops to

80 ℃ when you can point pulp. Spot pulp with a small spoon will be forward constantly stirring, slowly add gypsum water, when the soybean paste sticky spoon, stirring slowed down, add gypsum water speed also slowed down accordingly, until the soybean paste appeared corn-sized tofu particles, stop stirring, cover the pot, keep about half an hour on the pulp process.7, pulp pulp is the tofu brain poured in the wooden grid covered with cotton cloth, wrapped, with a heavy weight extrusion, squeeze out the water, usually not pressed too dry. Can not be pressed too dry, if the system of dried tofu, can be pressed to no water dripping out until. Pulp tofu has a long history. Plasma tofu processing production methods: soaking soybeans, grinding, filtering, cooking pulp, adding a small amount of salt brine, so that the protein coagulation of tofu into "flowers", and then put into a wooden frame, pressure to remove the excess water that is made into plasma tofu. The tofu made in this way is more tender than tofu made from gypsum and has no roughness.

Beginning less to do with a handful of beans to do experiments, my first time to make their own tofu did not strictly according to the program finally became salty soybean paste!
