In a large bowl, combine the wings, curry powder, turmeric, cayenne, soy sauce, canola oil, jalapeños, garlic, salt, and pepper. Toss to coat. Cover and refrigerate for at least 1 hour, or overnight.

Remove the marinated wings from the refrigerator and let come to room temperature.

Preheat grill to high heat. Place wings on the grill over indirect heat. Grill for 25-35 minutes, turning occasionally, until wings begin to brown and meat is cooked through. Move wings over direct flame to crisp the skin. Cook about 2 minutes on each side.

Serve with peach preserves for dipping
