I'm from the northeast. I think sauce beef and pigskin jelly are very good. This kind of cooked food is more suitable for high school students. Although it takes a long time to cook, it tastes good and nutritious. When I was young, the rural conditions were relatively poor at that time. Only during the Spring Festival will every household cook some pigskin jelly to eat. I remember that only pigskin jelly was filled with vegetables, and I still wanted to eat if I was not tired of it. Until now, pigskin jelly is also very popular with people, but unlike in the past, it can only be eaten during the New Year. I will order this dish when I go to a restaurant occasionally, and I will cook it on holidays. I'll make it clean and delicious. In addition, if I want to make my own pigskin jelly look good and delicious, I must steam it in a pot. The steamed pigskin jelly is especially clear and fragrant! Girls become less beautiful after eating them. As for sauce beef, many young people like it very much, but it is a little troublesome to cook it at home, and the cost is much higher than that of pigskin jelly, so even now we only cook it for important guests during the New Year or at home. These two cold dishes are hard dishes in the northeast, especially on the dinner table of most families' New Year's Eve!
