Wash, towel dry and trim the edges of the bhindi. Towel drying the bhindi is important or else the bhindi will turn slimy and soggy.
Slice each bhindi into lengthwise strips,4 to 6 strips from each bhindi. The thinner the crisper.
Add the bhindi in a large mixing bowl and add the spices - red chili powder or paprika, turmeric, coriander powder, chaat masala, salt.
Next add the gram flour and rice flours and coat the bhindi evenly with the spices and flours.
Sprinkle a tablespoon or two of water and coat the masala further. The bhindi shouldn't get soggy, so don't go overboard.
Preheat air fryer at 375 F.
Line the air fryer basket with a parchment paper and spread the bhindi in a single layer. Avoid overcrowding so it crisps properly.
Air fryer for 12-15 minutes. Keep an eye out after 10 minutes as air fryers vary from brand to brand.
One crispy, sprinkle extra chaat masala and serve immediately with lemon wedges.
Allow the bhindi to rest for a couple minutes and crisp further before indulging.
