Use this recipe to make our Grilled Oaxacan Shrimp appetizers.
Preheat oven to 425 degrees. Tightly wrap garlic in aluminum foil; bake until soft, about 45 minutes. Remove from oven; let cool. Squeeze garlic from peels; mix with remaining ingredients in a medium bowl. Transfer 1/3 of mixture to a blender; puree until smooth. Stir into remaining salsa. Refrigerate, covered, until ready to serve, up to 1 day.
