The scientific name of this dish you mentioned is "Amaranth". Flour and dough should be ready for use, as well as meat stuffing and a small amount of leeks. People's dishes should be washed and blanched (blanched for a while, not too long), then blanched in cold water to dry and chopped for later use. Wash and chop leek, wash and peel pork, chop it into meat stuffing, put it in a container, and add cooking oil (above appropriate amount).
