Here’s the deal, there are two ways to make this recipe. One way entails making your own red chile sauce from scratch, using dried ancho and guajillo chiles that you can usually only find at a specialty Mexican market. Even our local Whole Foods doesn’t carry these dried chiles. The second method starts with a base of canned red chile sauce, which is a little easier to find in a regular supermarket, and saves quite a few steps. I’ve made this recipe both ways. As you might expect, if you have access to the dried chiles and can make the time to make your own sauce base, it’s totally worth it for the extra intensity and depth of flavor. The good news is that if you can’t get a hold of the dried chiles, or you don’t have the time, canned red chile sauce works fine as a base for this sauce. Red chile enchilada sauce works too, though you may need to add some chili powder to it to increase the heat. In any case you are going to pump up the sauce a bit with ground cloves, cinnamon, and cumin. The sauce is slightly acidic. So, as with marinating chicken overnight with yogurt or buttermilk, a long marinating time in this sauce will help the chicken be surprisingly moist and tender. This recipes is adapted and inspired by Diana Kennedy’s Barbacoa de Pollo in The Art of Mexican Cooking. Bring to a simmer and let simmer for 5 minutes. Remove pan from heat and let cool. Marinate in the refrigerator at least one hour, preferably overnight. Brush the grill grates with olive oil. Make sure the chicken pieces are well coated on all sides with the paste-like marinade. Place the chicken pieces on the indirect heat part of the grill (not over a flame or coals). Cook, covered, for 25-30 minutes, turning the pieces over after the first 15 minutes. Try to keep the temperature in the grill around 350°F. Chicken is done when juices run clear, breasts have an internal temperature of 165°F and thighs 175°F. If you aren’t in a grilling mood, you can roast the chicken pieces in the oven. Preheat the oven to 350°F. Place the chicken pieces in a roasting pan, skin-side up. Cook for about 45-50 minutes, until breasts have an internal temperature of 165°F and thighs 175°F. Makes for great leftover chicken to cut up and put into tacos.
