1. Wash the bought black beans with clear water, and then soak them in clear water 10 hour or so.

2. Rinse the soaked beans again and drain them for later use.

3, the pot is hot, put the oil to heat, and then directly put the black beans into the pot and stir fry. You can fry more oil than usual, and black beans will be more brittle.

4. Stir-fry black beans until there is no bean smell. Cover the pot and cook for a while until the black beans are soft. In the meantime, open the lid and stir to avoid burning the bottom of the pot.

5. After the black beans are boiled soft, add pepper, onion and salt and continue to stir fry.

6. After collecting the juice, you can release it and use it to improve the taste. Just stir-fry the lobster sauce.
