Northerners prefer instant-boiled mutton to southerners, and the soup base in the north is generally very simple. Just eat a little onion and ginger at home. If you make it nourishing, you can put medlar, longan, mushrooms and the like, mainly depending on your own preferences.

Mutton and tripe need not be fried. The so-called fried tripe is to put the tripe in and eat it tender. In old Beijing, the way to eat at home is to wash the tripe (very important) and cut it into half-centimeter-wide silk, put it in boiling water with chopsticks, count for 5 seconds (it won't taste good after a long time), take it out and dip it in.
