EATING MY EMPIRE
Preheat broiler with rack set in upper position. Place tomatillos on a rimmed baking sheet and broil, turning once, until skins are blistered and charred, about 10 minutes. Remove from broiler. Transfer baking sheet to a wire rack and let cool on baking sheet.
Meanwhile, place onion, jalapeno, lime juice, cilantro, mint, and salt in the bowl of a food processor. Quarter tomatillos and add them, along with any accumulated juices from the baking sheet, to the bowl of the food processor; pulse just until combined.
Transfer salsa to refrigerator and let chill for at least one hour before serving and up to overnight.
