Specific how to eat can refer to the following steps:
1. Pick the appropriate amount of plum beans, clean and spare.
2. Boil a pot of water, add a little salt and oil when the water boils.
3. Blanch the beans in the water and cook for about 1-2 minutes after the water boils again.
4. Remove the blanched plum beans from the water, run them under cool water, then drain and set aside.
5. Add appropriate amount of seasonings (such as salt, soy sauce, vinegar, etc.) according to personal taste for cold or stir-fried dishes.
The above steps are for reference only, and it is recommended to make appropriate adjustments according to personal taste. If you are really not sure whether the plum beans are edible, you can ask a chef or diner with relevant experience.
