Weigh 100g dried soybean to prepare gluconic acid delta-lactone.

Second step

Soak soybeans in clear water for one night and they will swell completely. After soaking, the water was filtered off (after weighing, 100 g of dried soybeans was soaked in 236 g).

Third step

Add 1000ml of clean water to the soymilk machine.

Fourth step

Pour in the soaked soybeans and turn on the soybean milk function.

Step five

Filter the prepared soybean milk twice with a sieve (gauze or cloth bag will have better filtering effect)

Step 6

I measured the temperature of the filtered soybean milk, and it was only 72 degrees. The suitable temperature for making soybean milk to release lactone is about 85 degrees.

Step 7

Pour the soybean milk into the pot and heat it again. Cook on medium heat until you see the edge of the pot start to move, and then it will bubble. The temperature is enough, turn off the fire.

Step 8

Weigh 2g of δ -lactone gluconate in advance and melt it with a spoonful of cold water.

Step 9

Pour the molten glucono delta-lactone liquid into a pot, and stir while pouring.

Step 10

Cover and let stand for about 15 minutes (in order to keep the temperature, I put the whole soybean milk pot into a big pot filled with hot water, but this step should be ok without doing it)

Step 1 1

Prepare dried shrimps, shredded mustard tuber, chopped green onion, shredded laver, and light soy sauce (if you like sweetness, ignore this step and change it to your favorite sweetness).

Step 12

Simple method of homemade tofu

After the soybean milk in the pot is solidified, put it in a bowl with a large spoon, put shrimp skin, seaweed, mustard tuber and chopped green onion on the surface, pour in some soy sauce (or drop a few drops of sesame oil) and mix well to start.
