Have not made them yet but I've heard awesome reports on these:
2-3 habanero pepper, seeded and chopped (leaves seeds for spicier marinade)
3-4 jalapeno peppers, seeded and chopped (I leave seeds)
3-4 serranno peppers, seeded and chopped (I leave seeds)
1 1/2 cups soy sauce
2-5 good squeezes of honey
4 tablespoons packed light brown sugar
1 tablespoon granulated sugar
1 teaspoon cayenne pepper
1 -2 tablespoons crushed red pepper
1 teaspoon dried thyme
1/2 teaspoon ground ginger
2 cloves garlic, chopped
2 scallions, chopped
1/2 cup apple cider vinegar
2-3 fresh limes juiced
2 fresh oranges juiced
1/2 stick butter
3 pounds chicken wings
Combine the habanero, japs/serrano peppers, soy sauce, honey, both sugars, cayenne, red pepper, thyme, ginger, garlic and scallions in a
blender. Add the vinegar, lime juice and orange juice and blend until smooth. Place the wings in a large resealable plastic bag
and pour the marinade over them. Seal and refrigerate 4 to 6 hours (don't shorten - at least 4 hours).
Pour marinade in a heavy sauce pan and add half stick of butter. Reduce by 1/3 - 1/2.
On indirect heat, put wings down and cook at 350 for 45-60 mins. About every 5 mins, brush reduced marinade on wings.
