Chili Garlic Sesame Oil: Heat a large skillet over medium heat. Add 1/2 cup peanut or sesame oil and 1 head finely chopped garlic. Cook, stirring often until the garlic is fragrant and becoming golden/toasted, 8-10 minutes. Stir in the 3-5 tablespoons chili flakes (or more) and 3 tablespoons sesame seeds, cook 30 seconds to 1 minute more. Remove from the heat and very carefully transfer the oil to a heat proof bowl or glass jar.
