Rinse and drain the okra. Completely dry each okra individually with a kitchen towel or paper towels.

Cut the top and bottoms off of the okra. Then cut each okra into 4 quarters lengthwise. If the okra is thick you can also cut it into 6 pieces lengthwise.

Preheat the air fryer at 400° F for 5 minutes.

Place the cut okra in a medium-sized mixing bowl. Add turmeric, red chili powder, garam masala, salt, gram flour, rice flour, and ajwain seeds. Mix well. Add lemon juice and water. Mix well coating all the ingredients well to the okra. Add the cooking oil and mix well again.

Lightly spray the air fryer basket with cooking oil. Evenly place the okra in the air fryer basket without overcrowding. Having slightly layered okra is ok but spread out as much as possible within the basket. Cook in 2 batches if you have a smaller air fryer.

Cook at 350°F for about 10 minutes. Shake the basket, lightly spray the okra with cooking oil and then cook for an additional 2 minutes at 370 ° F.

Serve immediately with lemon wedges and ketchup.
