The best cold noodles are made of mung bean powder, and the taste and taste are first-class. The method is simple. Add water to mung bean powder to make paste, bring water to a boil in another pot, take a stainless steel plate or enamel plate, let it float on the water, and leave some oil in the plate to get a little paste. Rotate the plate to distribute the paste evenly. Put the plate in water, and the paste will change color and become cold noodles after a while. Just repeat it many times (the water in the pot must be kept boiling). After cooling, you can cook the seasoning. This is the authentic cold noodle method, which is not comparable to other cold noodle methods.
