@mackers1 - fairly simple and not sure at all authentic but very tasty!
Im not very good on quantities but something along these lines…
1 red and 1 white onion
1 green chilli (optional)
1 cup gram flour (you can use plain flour)
1 tbsp corn flour (if you have it)
1 tsp ground cumin
1 tsp ground coriander
1 or 2 tsp curry powder
salt and pepper
Thinly slice your onions, place in a bowl, sprinkle with salt and set aside for 15 mins.
Finely slice your chilli if using
Mix all dry ingredients in a large bowl. Squeeze your onions over the bowl so the liquid comes out and then drop the onions in and mix.
Slowly add water until the batter comes together. You don’t want it too wet.
Scoop up some mixture and form into a rough ball with your hands, add to air fryer basket - this amount gave me 5 in each basket of the ninja dual AF
Airfry for 4 mins and then turn then over and air fry for another 3/4 mins or until crispy.
I made them in the morning and then reheated in the air fryer for a couple of minutes after guests arrived.
