• Make-Ahead

Ingredients

1. Kosher salt
2. Cold water
3. One 3 1/2-pound chicken, cut into 8 pieces
4. 4 tablespoons unsalted butter
5. 1/2 cup minced onion
6. 2 large garlic cloves, minced
7. 1 1/2 teaspoons sweet paprika
8. 1 1/2 teaspoons pure ancho chile powder
9. 1/2 teaspoon crushed red pepper
10. 1/2 cup packed dark brown sugar
11. 1/2 cup cider vinegar
12. 1/2 cup tomato paste
13. 2 tablespoons unsulfured molasses

Directions

1. In a large bowl, dissolve 1/4 cup of kosher salt in 2 quarts of cold water. Add the chicken and refrigerate for 2 hours. 
2. Meanwhile, melt the butter in a medium saucepan. Add the onion and garlic and cook over low heat until softened. Add the paprika, ancho powder and crushed red pepper; cook, stirring, for 1 minute. Add 1 cup of water, the brown sugar and vinegar and bring to a simmer. Stir in the tomato paste and molasses and simmer over low heat, stirring occasionally, until the sauce is thickened, about 10 minutes. Season with salt and let cool. 
3. Light a grill or preheat the oven to 500°. Drain the chicken and pat dry, then grill over a moderately low fire, turning a few times, until just cooked through; about 25 minutes for the white meat; about 35 minutes for the dark. Alternatively, in the upper third of the oven, roast the chicken, skin side up, on a rimmed baking sheet, until just cooked through; 25 minutes for the white meat; 35 to 40 minutes for the dark. 
4. Set aside half of the barbecue sauce; brush the remaining sauce on the chicken. Continue grilling or roasting the chicken for 10 minutes, or until nicely glazed. Serve with the reserved sauce.
