Chop the dried peppers and fry them in a hot oil pan. Don't take too long, they will burn. Then you can add bean paste and stir fry, or you can add some spices such as pepper first. Or you can prepare dried peppers in a small pot first, and then heat them in the oil. Ok, this is mainly to avoid burning peppers. But be careful not to have water. Otherwise the hot oil will splash out.
