Method
- In a small pan, heat olive oil over medium heat.
- Add guajillo and arbol chiles, sesame seeds, peanuts, and garlic.
- Toast gently for 2–3 minutes, stirring often, until the chiles darken slightly and everything is aromatic but not burnt.
- Remove from heat and transfer all contents (oil included) to a blender or food processor.
- Add salt and apple cider vinegar.
- Blend until the salsa is cohesive but still textured—like a chunky chili oil.
- Let cool before transferring to a jar.
