Master 5 tips to easily make spicy and sour noodles with a fragrant aroma:

The first is to boil the powder and add salt, so that the salty taste comes first. Adding salt to the hot water in which the sweet potato powder is cooked can make the sweet potato powder absorb the salty taste during the ripening process, so that it will not taste unpleasant.

The second is to stir-fry the raw materials to fully release the aroma. Many hot and sour noodles are made by putting onions, ginger, garlic, and mustard directly into the soup. But if these ingredients are stir-fried in oil, the aroma can be fully released, and then added with water to cook into soup, the aroma will be absolutely fragrant. .

The third is to add vinegar first and then water, so that the flavors are completely integrated. If you pour the mature vinegar directly into the hot and sour noodles, you will inevitably feel that the sourness is particularly harsh. However, if you pour the mature vinegar, light soy sauce, and chili noodles into the fragrant onions, ginger, and garlic, and then add water to boil, the resulting soup will be sour and spicy. Salty and fully integrated.

Fourth, return to the pot for a while to allow the noodles to fully absorb the flavor. Pour the cooked sweet potato powder back into the soup and cook for a while, so that the sweet potato powder can fully absorb the flavor of the soup without completely separating the flavor of the soup powder.

Fifth, add sugar to the pot to highlight the hot and sour taste. When cooking spicy and sour dishes, adding a little sugar before serving is definitely the finishing touch to enhance the freshness and flavor.
