Second, Liu An's Biography of Li Sao is the earliest work that China praised Qu Yuan and Li Sao.
Thirdly, he once recruited thousands of people to write Lie Hong, also known as Huainanzi, which is an epoch-making academic masterpiece in the history of China's thought. Liu An is the first practitioner in the world who tried to take off in a hot air balloon, and also the founder of China Tofu.
Fourth, the invention process of tofu:
1, tofu was invented, not discovered. Just as an alchemist invented explosives, tofu was also invented during alchemy.
2. Huainan, where Liu An's fief is located, is rich in soybeans, and soybean milk ground from soybeans is also one of the main local diets.
3. When Liu An was making an alchemy, he sprinkled the soymilk he drank on the gypsum used for making an alchemy, and the soymilk condensed into tofu, and delicious tofu appeared.
Five, the practice of tofu:
1. Soak the soybeans for about eight or nine hours until the soybeans are completely soaked.
2. Add water to soybeans and grind them into soybean milk with a cooking machine or soymilk machine (cold drink function). Find a clean cotton cloth and put it in a bigger basin.
3. Pour the soybean milk into the cotton cloth with a sieve.
4. Filter out the bean dregs and drain them as much as possible.
5. Put the soybean milk into the pot, heat it on low heat, and skim off the floating foam on the surface with a spoon.
6, slow stew, stir with a large spoon while cooking, to avoid burning the pot.
7. Turn off the fire until the soybean milk boils.
8. At this time, 4 g of lactone was mixed with 25 g of warm water to dissolve it.
9. Remove the soybean milk from the fire and naturally cool it to 80-90 degrees. You can use a thermometer, which is more accurate. It doesn't matter without a thermometer. It takes about a minute in this weather.
10, pour in the lactone solution, stir quickly, and the action must be rapid. About three or four seconds, cover the pot immediately and start stewing.
1 1. Cover with soybean milk and stew 15 minutes. When you open the lid, you will find that everything is solidified. This is the tofu brain we usually eat.
12, you can take out a little to make tofu brain.
