Heat the bbq to medium-high. Season the wings with Salt & Pepper.

Grill the wings, covered, turning occasionally, until they are golden brown, crispy and completely cooked through, about 20 minutes. Keep a close eye on the BBQ: if there are flare-ups or the wings begin to burn, move the wings to a cooler part of the BBQ or reduce the heat.

Just before the wings are cooked, make the sauce. Combine the butter and garlic in a skillet and place on the BBQ. Cook for about one minute until the butter is melted. Stir in the hot sauce, salt, onion powder, chilli powder and sugar.

Dip the cooked wings in the sauce and serve immediately.
