A traditional salsa verde recipe with an extra little punch from seasonal Hatch chiles. If you cannot get Hatch chiles, you can substitute 1 or 2 jalapeño peppers (seeded) to give the salsa some heat, if desired.
Place the tomatillos in a medium saucepan, cover with water and bring to a boil over high heat. Boil until they turn brownish-green and are soft, 5 to 7 minutes. Remove with a slotted spoon and immediately place into a bowl of ice water.
Place the drained tomatillos, Hatch chiles, cilantro, onion, garlic, lime juice, salt and cumin in a blender and puree until smooth. Place in an airtight container and refrigerate for at least 1 hour before serving. The salsa can be refrigerated for up to 4 days.
