How to Make Chili Oil

Step 1

Gather all the aromatics you plan to use. Place oil and selected aromatics into a pot with at least two inches of clearance between the oil and the rim of the pot. If using minimum aromatics, 1 ½ cups of oil should do it. If using all the aromatics, you can add up to 3 cups of oil.

Step 2

Set it over medium heat to start, then progressively lower it to medium low or low heat as the oil comes to temperature. The oil should be at about 225° F / 110° C and causing small bubbles to slowly rise from the aromatics. If you notice the spices sizzling more vigorously than that or turning dark too quickly, take it off the heat until it cools down. If you are not achieving small bubbles, you can slowly move the temperature to 250° F, but 200-225° F is safest to prevent burning. Infuse the aromatics this way for a minimum of 30 minutes, or up to 1 hour for best results.

Step 3

While the oil is infusing, prepare your Sichuan chili flakes by placing them in a heatproof bowl. If you used 1½ cups of oil, ¾ cup of chili flakes is best. For 3 cups of oil, use 1¼ cups of chili flakes. You can experiment within this range (if you like more oil and fewer flakes, for instance).

Step 4

Generally, the oil should be between 225-250° F (110-120° C) when pouring over the chili flakes. If you like a darker color, opt for 250° F/120° C. If your chili flakes are already super roasted, you may want to be closer to 225° F/110° C. Carefully pour the hot oil through a strainer onto the chili flakes. Stir to evenly distribute the heat of the oil.

Step 5

Stir in the salt, and allow the chili oil to cool. Store in airtight containers in the refrigerator. Always use a clean utensil when handling to prevent spoilage. It can last for up to 6 months if handled in this way.
