Can I use fresh chiles instead of dried ancho chiles?
Fresh chiles will change the flavor profile significantly—dried anchos provide the signature smoky, deep heat. If substituting, use 3–4 fresh poblanos or Anaheim chiles, but expect less smoke and more brightness.
How do I know when the tomatoes are properly roasted?
Roast until the skins blister and char in spots and the tomatoes begin to collapse, about 15–20 minutes depending on your oven. The flesh should be soft and the edges darkened.
What's the best way to rehydrate the dried chiles?
Pour 1 cup of boiling water over the chiles and let them steep for 10–15 minutes until softened, then drain. Reserve soaking liquid if a thinner salsa is preferred.
Can this salsa be made ahead?
Yes. Store in an airtight container in the refrigerator for up to 5 days, or freeze for up to 3 months. Flavors deepen after 24 hours.
How spicy is this salsa?
Ancho chiles are mild to medium heat. Remove the seeds from the chiles before blending for a milder result, or add 1–2 dried chipotles for more smoke and heat.
