The composition of tofu is 700 words.

Grandma village is a well-known tofu village. On Sunday, I went to my grandmother's house to play. I made tofu myself.

First, pick soybeans. Grandma and I picked out all the spotted rotten soybeans that were soaked in the cauldron yesterday to ensure that all the soybeans were round and full, so that the quality of tofu can be guaranteed. After that, grandma washed the soybeans, and then added a proper amount of water in proportion.

Then, squeeze the soybean milk. Grandma pressed the' switch' of the bean curd machine, and with a bang, I scooped up a small pot of soybeans and poured them into the population above the bean curd machine. As soybeans slowly fall, thick white soybean milk flows out of the tube on the left side of the bean curd machine and drops into the big basin below people; In the tank on the right, the bean dregs came out and fell into another big basin below. I bent down again and again to scoop beans and add beans. There are fewer and fewer soybeans in the cauldron and more and more soybean milk, but I am getting more and more tired. Grandma said lovingly, "Nizi, have a rest." I stubbornly insisted on finishing it. Finally, after adding the last pot of beans, I sat on the ground like a broken shelf. Grandma didn't turn off the machine, but scooped up the bean dregs. Seeing that I was puzzled, grandma smiled and said, "The bean dregs have to pass twice before they can be ground clean."

Then, my grandma and I poured the soybean milk into the cauldron and began to cook. The golden flame happily licked the bottom of the pot, the soybean milk boiled, and bubbles appeared in the pot. Grandma stopped cooking and went into the house to get a bottle of glucose solution. She poured it into the pot and said to me, "Tofu used to be made of brine, which was not only bitter, but also harmful to health." Now people are turning to glucose. " "What does glucose do?" I asked curiously. "It can coagulate and turn the cooked soybean milk into tofu." Grandma stirred the soybean milk with a stick and said.

Finally, my grandma and I scooped out the soybean milk and poured it into a big basin to cool. At this time, soybean milk has almost turned into a white solid. Grandma scooped the white solid into two rectangular wooden frames, covered with cloth, wrapped in cloth and pressed it on the boards and stones. So you have to wait at least two hours for the water to seep out, and the tofu will be ready.

Through making tofu this time, I deeply realized that cherries are delicious but trees are difficult to plant, and tofu is delicious but difficult to make.
