Put a proper amount of oil in the pot until there are no bubbles in the oil. Smoke, turn off the fire, add ginger and onion (the amount depends on the amount of oil, a little more) and put oil. When all the onions turn yellow, you can take them out. Then put the prepared dried green pepper and a small amount of red pepper into the oil, heat the green pepper by constantly adjusting the oil temperature, and melt the hemp taste of the green pepper into the oil. When there are spices such as nutmeg, you can put them in (the leaves are put last), and the fragrance of nutmeg will melt in the oil. Keep turning the green pepper, and it will slowly turn from cyan to black. When the green peppers are almost all black, you can turn off the fire. Turn off the fire, add the fragrant leaves and continue to turn. Then wait for the oil to cool slowly, seal it after cooling, and add more green peppers if you want to get numb.
