Pat chicken wings dry using paper towels. Make sure that they are as dry as possible. If you have any extra time, leave wings to dry out in the fridge for around an hour, uncovered.
Preheat the oven to 210C/410F. Line baking sheet with foil, or use parchment.
Mix salt, garam masala, baking powder, and sugar in a large bowl. Add chicken wings into a bowl, drizzle olive oil on top and mix everything, making sure to cover the wings evenly.
Layer wings on a baking sheet, making sure they are not touching.
Bake for 30 minutes, flipping halfway through.
Serve with lime wedges, topped with chopped scallions.
Notes
This recipe also works in an air fryer if preferred. Just add the wings in a single layer and cook on the highest heat setting for 15 minutes before flipping, and again for another 10- 15 minutes to finish cooking.
