Can I make this salsa ahead of time?
Yes. Store it in an airtight container in the refrigerator for up to 5 days. Flavors actually improve after a few hours as ingredients meld.
How do I control the heat level?
Remove the seeds and membranes from jalapeños and serranos before blending for milder salsa, or add more serranos for extra heat.
Should I use fresh or canned tomatoes?
The recipe calls for fresh Roma tomatoes. Fire-roasted canned tomatoes work as a substitute if fresh aren't available, but drain excess liquid first.
Why is my salsa too watery?
Roma tomatoes vary in moisture. If excess liquid pools, drain some before pulsing, or reduce the 1/4 cup water by half.
Can I blend this instead of using a food processor?
A blender will over-process and make it too smooth. A food processor gives you control over the chunky texture. Pulse in short bursts instead of continuous blending.
