1 tomatillo, husk removed, and chopped
2 tablespoons chopped cilantro
1 teaspoon lime zest (about 1 small lime)
1 teaspoon chopped fresh garlic
½ to 1 teaspoon finely chopped jalapeño pepper
½ teaspoon kosher salt
8 tablespoons (1 stick) unsalted butter, softened
1. Place the tomatillo, cilantro, lime zest, garlic, jalapeño pepper, and salt in a food processor and thoroughly combine. Add the butter and combine until just blended.
2. Scoop the flavored butter onto a piece of waxed paper and roll into a cylindrical shape. Refrigerate for at least 1 hour.
3. Slice off “coins” of the butter to serve with boiled or grilled corn.
