Put a small amount of oil in the pot, the oil will smoke
Put the pepper on the pan, and occasionally turn the pepper over and use a spatula to gently press the skin to fry the skin.
Put a little vinegar in the pot, a spoonful of bean paste, stir fry, turn off the fire
I think the bean paste is quite salty. . . So I didn’t put salt, the saltiness is just right.
