Add chopped eggplant and onion to a large mixing bowl.
Add salt, dry mango powder, paprika, and any other spices you are using.
Mix well and keep aside for 10–15 minutes. This helps the eggplant and onion release moisture.
Add red lentil flour, gram flour, chopped coriander leaves, and oil.
Mix until the eggplant and onion pieces are well coated with the flour.
In a small bowl, mix 2 tablespoons water with a small pinch of baking soda.
Add this water slowly to the pakora mixture.
Mix again to form a thick, sticky mixture. Do not make it runny.
Preheat the air fryer to 180°C for 3–5 minutes.
Line the air fryer basket with perforated parchment paper.
Place small portions of the pakora mixture in a single layer.
Air fry at 180°C for 18–20 minutes, or until golden and crisp on the edges.
Brush or spray a little oil halfway if the pakoras look dry.
Serve hot with green chutney, ketchup, or yogurt dip.
