Boiling method of red oil:
About 500 grams of vegetable oil and rapeseed oil can be replaced by soybean salad oil. Boil it in a pot, put it in a cool place, add scallion and ginger pieces, turn the fire to the minimum when you see fine foam rising around the ginger onion, then add pepper, clove, cinnamon, fennel, tsaoko, star anise, fragrant leaves, Lithospermum and Chili noodles, stir well and cook for 30-40 minutes. After 30-40 minutes, add white sesame seeds, continue to cook for 30-40 minutes, and turn off the fire. Air the boiled red oil until it is cool, and then pour it into a container with oil and materials.
