Can I make this salsa without roasting the ingredients?
Roasting is essential to this recipe—it caramelizes the vegetables and chiles, developing the smoky, deep flavor that defines roasted red salsa. Raw ingredients will produce a different, less complex result.
How spicy is this salsa?
Chiles de árbol are moderately hot (15,000–30,000 Scoville units). Reduce the amount to 8 chiles for milder heat, or increase to 15 for spicier salsa.
How long does roasted red salsa keep?
Store in an airtight container in the refrigerator for up to 5 days. Freeze in ice cube trays for up to 3 months for easy portioning.
What's the best way to roast the ingredients?
Use a cast-iron skillet or comal over medium-high heat, turning vegetables and chiles frequently until charred and softened (5–8 minutes). Alternatively, roast on a grill or under a broiler.
Can I adjust the thickness of this salsa?
Yes. Add more water for a thinner consistency or reduce water and blend less for a chunkier texture.
