Step 1

In a medium saucepan, melt the butter. Add the chopped sweet onion and cook over moderate heat, stirring occasionally, until the onion is softened and lightly browned, about 5 minutes. Add three-fourths of the minced habanero chile and cook for 1 minute, just until softened. Scrape the onion and habanero into a blender, add the cherry preserves and lime juice and puree until smooth. Return the cherry glaze to the saucepan and bring it to a boil over moderately high heat. Stir in the remaining minced habanero chile and season the glaze with salt and black pepper. Transfer the glaze to a small bowl.

Step 2

Light a grill or preheat a broiler and position a rack 8 inches from the heat source. Season the chicken wings all over with salt and black pepper and grill over moderately high heat, turning occasionally, until lightly charred and crispy, about 20 minutes. Alternatively, broil the wings for about 20 minutes, turning occasionally, until they are crispy.

Step 3

Transfer the chicken wings to a large bowl and toss with one-third of the cherry glaze. Return the wings to the grill or broiler and cook, turning once, just until sticky and caramelized, about 2 minutes. Return the chicken wings to the bowl and toss with another one-third of the cherry glaze. Transfer the glazed chicken wings to a serving platter and serve with the remaining glaze on the side.
