Bottled hot-pepper sauce and bubbling cola give the chicken wings a sweet hotness in this appetizer.
Place the chicken wings in a large heavy, self-sealing plastic bag set in a shallow dish. Pour the 12-ounce can of cola over the chicken wings. Seal bag. Marinate in the refrigerator for at least 1 hour or for up to 4 hours, turning bag occasionally. Drain the chicken wings, discarding the cola marinade. Return wings to bag; pour the hot-pepper sauce over the chicken wings. Close bag. Marinate in the refrigerator for 4 to 24 hours, turning bag occasionally. Drain the chicken wings, discarding the hot-pepper sauce marinade.
In a very large skillet, heat the oil over medium-high heat. Cook 12 chicken wings in the hot oil over medium heat till brown on all sides. Remove from skillet; place in a well-greased, foil-lined large roasting pan. Repeat with the remaining chicken wings, adding more oil, if necessary. Reserve the pan drippings. Bake chicken wings in a 450 degree F oven for 20 minutes or till tender and no longer pink.
In the same skillet, cook and stir garlic over medium heat for 1 minute. Add the 1/4 cup cola. Bring to boiling; reduce heat. Simmer, stirring occasionally, 1 minute or till liquid is reduced to about 2 tablespoons. Whisk in butter till melted and the sauce is thickened. Keep warm.
To serve, spoon Avocado Salsa into the center of 4 or 6 dinner plates. Place 4 or 6 of the chicken wings around the salsa. Drizzle the warm sauce over the chicken wings.
