What snacks can be made with flour?

I won’t mention some familiar ones. I personally like to eat 1 noodles and 2 fish roe noodles. The method is 1: mix the noodles and water together to form a paste, boil half a pot of water, and put some seasoning or salt in it. MSG, wait for it to boil, pour the batter in, and stir until it forms lumps. You can also add some cabbage when it is almost ready, it is delicious; 2: (there is one in the restaurant) there is no fish roe in the noodles, but the lumps in the noodles look like fish roes. It's so small, I can't do it myself
