1 1/2 cups mango, peeled, pitted and roughly chopped
3/4 cup fresh cilantro (loose pack, not chopped, stems and all)
2 chipotle peppers in adobo, plus 1 tablespoon adobo sauce
2 tablespoons unseasoned rice wine vinegar
4 cloves garlic, peeled
2 tablespoons fresh lemon juice
1 tablespoon canola oil, plus extra for grill
2 teaspoons kosher salt
1 teaspoon freshly cracked black pepper
2 pounds chicken thighs and drumsticks, bone in, skin on

Put the mango, cilantro, chipotle, vinegar, garlic, lemon juice, 1 tablespoon of oil and salt and pepper, in a food processor and puree until smooth. Adjust seasonings, to taste.


Add the chicken with half the mango mixture to a resealable plastic bag, and massage to coat the chicken with the sauce. Refrigerate at least 6 hours to marinate.


Put the other half of the mango mixture into a small saucepan and simmer over low heat until thick, stirring often, about 15 minutes. Set some of the simmered chipotle-mango sauce aside to serve on the side and baste the chicken every few minutes with the rest of the sauce.


Preheat a grill or grill pan to medium-high heat and brush with canola oil. Remove the chicken from the marinade and put on the grill.


Grill the chicken turning and basting about every 5 minutes until cooked through, about 20 to 25 minutes. Transfer to a serving platter and serve with the reserved mango sauce.
