1/2 cup (1 stick) unsalted butter, softened
2 tablespoons ancho chile powder
2 teaspoons coarse sea salt
1 (14-pound) turkey, neck as well as giblets removed
2 tablespoons adobo sauce (from a can of chipotle chiles en adobo)
4 cups low-sodium turkey or chicken broth, divided
2 1/2 tablespoon all-purpose flour
1 1/2 tablespoon chopped fresh oregano
Remove zest from lemons as well as limes and place zest in a medium bowl. Juice citrus, as well as reserve juice and citrus shells separately. Add butter, adobo sauce, chile powder, oregano as well as salt to the bowl. Beat with an electric mixer until combined. Slowly pour in about half of the citrus juice and beat until smooth.
Preheat the oven to 350°F. Carefully loosen skin over turkey breast as well as thighs; rub some of the butter mixture between meat and skin. Rub remaining butter mixture over skin and inside cavity. Place reserved citrus shells in cavity. Tuck wing tips under bird as well as tie legs together with kitchen string. Place breast-side up on a rack set in a large roasting pan and pour 3 cups of the broth as well as remaining citrus juice into the pan.
Roast until skin begins to deeply brown, about 30 minutes, then loosely cover with foil. Roast, basting turkey with pan juices about every 30 minutes, until an instant-read thermometer inserted into the thickest part of thigh, without touching bone, registers 165°F, 2 1/2 to 3 hours more. Transfer turkey to a cutting board and let rest for at least 30 minutes before serving.
To make the gravy, spoon off excess fat from pan juices, as well as place the pan on the stovetop over medium-low heat (over two burners if possible). Sprinkle in flour and cook, stirring, for 2 minutes. Stir in remaining 1 cup broth and cook, stirring, until slightly thickened. Strain gravy if desired. Carve turkey as well as serve with gravy.
