Homemade Chinese Sichuan Hot Chili Oil

Put 2 tablespoon red chili flakes and 1 tablespoon sesame seeds into a ceramic or ceramic container, mix thoroughly. Heat oil in pan, when the oil gets a little smoky, turn off the heat immediately. Pour hot oil onto chili flakes and sesame seeds, stirring while pouring. (The process is basically completed here. The following steps are optional. They are used to enhance the chili oil’s bright, red color.) Divide remaining red chili flakes into 3 portions, each containing 1 teaspoon. Let the oil cool a little, then add 1 teaspoon chili flakes, stir to combine. Let the oil cool a little more, then add 1 more teaspoon chili flakes and stir to combine. When the chili oil has cooled down to room temperature, add the remaining 1 teaspoon chili flakes and mix well. Note: Do NOT use chili powder, fine chili powder becomes bitter when mixed with hot oil.
