To make Chili sauce douchi like Laoganma, you need dried douchi.
Steps:
Fry black beans in hot oil for a while, being careful not to fry. When they are fragrant, add a proper amount of dried Chili noodles, and be careful not to fry them in medium heat, otherwise they will not taste good. There must be more oil. You can drown all the lobster sauce and pepper, and start to add salt, monosodium glutamate, a little garlic and other seasonings when you are half fried. All of them can be bottled after frying, with long shelf life and convenient eating. But if you haven't done it yet, you'd better not do it, because it requires a high degree of mastery of the temperature. In the process of frying, you can also add various seasonings according to your personal preferences. You can put more monosodium glutamate.
