FAQs
Can I use other types of peppers instead of serrano?
Yes, you can substitute jalapeño peppers for a milder heat or habanero peppers for a spicier salsa, adjusting quantities to taste.
Is it necessary to roast the vegetables?
Roasting adds a smoky flavor and softens the vegetables, enhancing the salsa’s taste, but you can use raw ingredients if short on time for a fresher, sharper flavor.
