Cooking Steps

Melt the lard in heavy medium saucepan over medium heat. Add onion and sauté until tender, about 10 minutes. Add garlic and sauté 1 minute. Add tomato sauce, maple syrup, soy sauce and red pepper flakes; bring just to a boil. Reduce heat to low and simmer until sauce thickens slightly, about 20 minutes. Stir in the vinegar; season sauce to taste with salt and pepper. Reserve about 3/4 of a cup for the chicken wings, and store the rest in an airtight container in the refrigerator for a later use.
While the sauce is simmering, prepare and heat your grill, depending on type – if using charcoal, make sure you have a bed of hot coals, covered in ash, spread evenly beneath the grate. Raise the grate to between 4 and 6 inches above the coals/heat.
Rinse the chicken wings and dry then with a paper towel. Place them in a large bowl and sprinkle them with the seasoning mixture/dry rub, tossing them frequently to coat them evenly. Place then over the coals/heat and cover. Cook, turning occasionally, for about 20 minutes or until the chicken is no longer pink near the bone. Baste with the barbecue sauce for the last 5 minutes.
Remove to a platter and allow the chicken to rest for 3 to 5 minutes before serving.
