Ingredients for making onion pakora.
In a large mixing bowl, add the onion slices, green chilli, cilantro, and salt. Mix well and squeeze the mixture so that the onion releases moisture. To this, add the besan flour, rice flour, chili powder, ground cumin, salt, and hot oil. Give it a good mix. Slowly add one tablespoon of cold water at a time and bring it together to form a thick and sticky batter. You will not need more than ¼ cup of water.
Take small portions of the batter (around 2 tablespoons) and place it in the basket. Place more pakora batter in a single layer, making sure they do not touch each other.
Air fry at 350 F (180 C) for 8-10 minutes. Keep an eye after 7 minutes mark. Spray oil on the top. Then, increase the temperature to 400 F (200 C) and air fry for another 2-3 minutes, until they are golden brown.
