Laolu (wa) spread (sa with two tones) is a local food in Shaanxi that is similar to gnocchi, but the gnocchi inside are much larger than the gnocchi. The dough pieces are pointed at both ends and rounded in the middle. The shape is like a crow's head, so it is named Lao Lusa. The imagination of Shaanxi people is indeed admirable.

The method of making pimple soup is to stir the flour into a paste. After the pot is boiled, use chopsticks to cut it into chunks or strips and cook it.

To make the authentic Laolu Sa, first knead the dough with water into a soft dough, let it rest for a while, put the dough in a basin and flatten it, and pour a little water around the dough, just like soaking the dough. Feel it, and then knead the dough, boil the water in the large pot of the farmhouse stove, and knead the dough into pieces in the palm of your hand. Due to the water, some regular and uneven dough pieces will not be kneaded, and there will also be some stickiness. The size of the cotton wool can be adjusted according to your preference. In the end, there will be a lot of washed out starch in the basin. Pour it into the pot together, so that the cooked Laolu Sa suddenly looks like a thick pot. It bubbles lively, and when you stir it with a spoon, you can feel the large and large pieces of dough in it.
