What type of chiles should I use for Sichuan chili oil?
Use authentic Sichuan ground chiles (also called Sichuan chili powder). These are distinctly different from cayenne or generic chili powder and provide the characteristic numbing, fragrant heat that defines the dish.
Can I use a different oil besides canola?
Canola oil is traditional for its neutral flavor and high smoke point. Neutral oils like vegetable or peanut oil work similarly, though avoid strong-flavored oils like sesame or olive oil that will overpower the chile.
How long does homemade Sichuan chili oil last?
Store in an airtight glass jar at room temperature for up to 2 months. The flavor remains strong and fresh when kept away from direct light and heat.
Do I need to strain the chiles from the oil?
No—the ground chiles remain suspended in the oil. This is characteristic of authentic Sichuan chili oil and provides maximum flavor and texture with every use.
Can I scale this recipe up or down?
Yes. Maintain a 1:1.13 ratio of ground chiles to canola oil by volume. For smaller batches, simply reduce both ingredients proportionally.
