"Quack-quack" is actually the "crispy rice" in Tianshui dialect. In fact, quack is a kind of buckwheat noodles made of buckwheat. However, it is obvious that its soba noodles lack charm and are still called "delicious", which is justified. Boil a pot of boiling water, sprinkle buckwheat starch evenly in the pot and stir. Stir it and the buckwheat noodles will become solid. The prepared buckwheat noodles have soft taste.

Daidai is actually a kind of potato flour, which is made of potato starch and soy sauce. Cut the bean jelly into pieces, and the seasoning is the same as quack. Pepper and pepper oil, sesame sauce, garlic water, vinegar and other seasonings are all common combinations. It's just that the taste is different from croaking softness, and the taste is elastic, a bit like jelly.
