Black beans can be directly fried without soaking, but the following points should be noted:
1. Before frying black beans, it is best to wash them with clean water to remove impurities and dust.
2. When frying black beans, you need to stir fry them with medium fire for a while to make their surface slightly discolored, and then stir them with high fire until they are fully cooked.
3. When frying black beans, it is better to add some seasonings, such as salt, pepper, and five spice powder, to increase the taste.
4. The time of frying black beans should not be too long, or they will become hard and unpleasant.
In a word, although it is OK to stir fry black beans without soaking, it is better to soak them in advance, which can not only shorten the cooking time, but also better absorb spices and nutrients.
