Ingredients

1 cup canned unsweetened coconut milk (not low-fat)

1 tablespoon vegetable oil, plus more for grates

4 boneless, skinless chicken breast halves, (6 to 8 ounces each)

Coarse salt and ground pepper

2 jalapeño chiles

1 tablespoon fresh lime juice

Cooked white rice (optional)

Lime wedges, (optional)

Preparation

In a small saucepan, bring coconut milk to a gentle simmer; cook, stirring occasionally, until thickened and reduced to 1/2 cup, about 20 minutes.

Meanwhile, heat grill to high; oil grates. Rub chicken all over with oil; season generously with salt and pepper. Place chicken and jalapenos on grill; cover. Cook, turning occasionally, until chicken is cooked through and jalapenos are blackened all over, 12 to 16 minutes.

Transfer chicken to a platter; keep warm. Peel jalapenos, rubbing off the blackened skins with a paper towel; transfer to a blender. Add reduced coconut milk, lime juice, and 1/2 teaspoon salt. Blend on high speed until smooth.

Slice chicken crosswise into 4 or 5 pieces, and place on plates; spoon coconut sauce over the top. Serve with rice and lime wedges, if desired.
