Wash lard with soap

First, there are too many kinds of leeks. In the era when educated youth went to the countryside, those educated youth who were sent from cities to the countryside asked what they shouldn't have asked and did what they shouldn't have done because of the disconnect between knowledge and practice. At an educated youth point, a newly arrived educated youth saw the production team leader and suddenly asked, "Why are there so many leeks planted in the fields and fields of the production team besides vegetables and potatoes?" The captain said: "What is planted is rape, an oil crop, not a vegetable, but a potato. We don't know what potatoes are. It seems that leek is wheat, and it is easy to distinguish between leek and wheat. Leek tastes delicious, but wheat seedlings are not. You can't use wheat seedlings as leeks. " Second, wash lard with soap. There is also an educated youth in the educated youth point. I bought several kilograms of lard from the food store. In order to eat hygienic lard, I took the lard I bought to the river to wash it, but there was no way to wash the dirt off the lard. They think soap can remove dirt. As long as lard is washed with soap, they are not afraid that it will not wash off. Some people hurried home and brought soap to wash lard. No matter how they wash, they can't get rid of the dirt. They went to ask the members, why can't soap wash the dirt off the lard? Fang didn't laugh at them, but told them sincerely, "The lard you bought doesn't need washing. There are other dirty things on it. Take it off by hand first, then cut it into small pieces with a kitchen knife and put it in a pot for refining until the lard residue is dry. " Refined oil is clean. "
