Do you use cold water or hot water to make dough? Do you need yeast in the dumpling skin?
without yeast, put the flour into a basin, and add cold water and flour. The dumpling skin made in this way is more elastic, resistant to boiling and not easy to break. Adding some salt to the dough can make the gluten smooth. (If you want to make steamed dumplings, you should use hot water to make noodles. jiaozi will be softer. If you cook dumplings, you have to use cold water. )
