1/4 cup packed dark brown sugar
3 cups water
4 slices lemon (1/4 inch thick)
1 Tbs. black peppercorns
1 Tbs. mustard seeds
3/4 cup strong brewed coffee
4 boneless skinless chicken breast halves2 T olive oil
To make the brine, combine the salt, sugar, water, lemon, peppercorns, and mustard seeds in a medium saucepan and heat over medium heat, whisking occasionally, until the salt and sugar dissolve, about 5 minutes. Transfer to a medium-large bowl, add the coffee, and refrigerate until cool, about 15 minutes. Put the chicken breasts in the brine and refrigerate for 2-3 hours.
Heat a gas grill to high or prepare a hot charcoal fire.
Make a dry rub mixing the spices. If you don’t have adobo seasoning, feel free to improvise mixing flavors you are fond of 😉 Drain the chicken and blot dry with paper towels. Lightly brush both sides with olive oil, and coat one side with the dry rub mix. No need to make a thick coating, just sprinkle the spices all over. Place the breasts on the grill, spice side down, grill for about 3 minutes, rotate them 45 degrees (do not flip them yet) to get a nice pattern of marks, continue grilling 4 additional minutes. Now flip the breasts and grill 4 minutes with the spice rub up.
Remove from the grill and tent with aluminum foil for a few minutes before slicing at an angle.
