Method
Roast the poblano and tomatillos until softened and lightly charred.
Let the poblano cool slightly, then remove the stem and seeds.
Add the poblano, tomatillos, onion, cilantro, lime juice, and salt to a blender or food processor.
Blend until the salsa reaches your preferred texture.
Taste and adjust the seasoning before serving.
Notes
For less heat, remove all poblano seeds; refrigerate leftovers in a covered container for up to 3 days.
