Preheat your oven to 425ºF. Pat dry your wings and optionally season with salt. Toss your wings in cornstarch or baking powder, then arrange on a single layer on a rack over a foil covered baking sheet
Bake the wings for 40-50 minutes, turning after 30 minutes.
While the wings are baking, make the sauce by seeding, then blending the habenero, pineapple, mango, and lime juice until smooth.
Transfer the sauce to a small saucepan. Bring to a boil, then simmer for 10 minutes. Taste and temper with the sugar if you find the sauce too tart.
Toss the wings in sauce, then enjoy immediately.
