Can I use regular green tomatoes instead of tomatillos?
No. Tomatillos have a tart, distinct flavor essential to this salsa. Green tomatoes are starchy and won't provide the same acid or brightness.
Should I char the tomatillos or just boil them?
Boil the tomatillos until soft, then char only the tomato and chiles. Charring tomatillos makes them mushy; boiling softens them evenly while retaining structure for blending.
How spicy will this salsa be?
Serrano chiles and chile de árbol both pack heat. Remove seeds and ribs from chiles before charring to reduce spice, or add them gradually and taste as you blend.
Can I make this salsa ahead?
Yes. Store in an airtight container in the refrigerator for up to 5 days, or freeze for up to 3 months. Thaw in the fridge before serving.
What's the best way to char the tomato and chiles?
Use an open flame on a gas stove, a cast-iron skillet over high heat, or a grill. Char until blackened and blistered on all sides, about 2–3 minutes per side.
