Toss wings with sauce before serving. If grilling, you can also brush the wings with the sauce just before removing.
For the sauce (makes enough for 4-5 batches of wings)
Place the peaches, jalapenos, onion and ginger into a food processor. Pulse a few times. You want to shred the ingredients but not puree them.
Transfer to a sauce pan. Add remaining ingredients. Bring to a boil then reduce to a simmer. Continue simmering, stirring occasionally until thickened.
