Plum and pork buns, there are a few points to note. Plumbs are sifted several times, filtering out the dust that's hidden in them; fertilizing in the pots after a soft bubble; and screeching in three, seven or four, six fat ones. Because prunes are more oily, less fat and more meat, so they taste soft and sweet. Skin is good with hair. The ratio of flour to yeast is 100:1-2, cool water and face in summer, and warm water and surface in winter. When the noodles are twice the size of their original size, they are filmed with their hands, they are lifted, and the tissue below them is organized in an evenly long strip, and the bubbles are equally distributed。
