Take about 2 cups of water in a pressure cooker, add very well washed baby potatoes (skin intact) and small beetroot cut into pieces. However adding beetroot is completely optional.
Pressure cook for 1 whistle only.
Take the potatoes out in a bowl and leave them to cool completely. You can cut into half the big potatoes.
In a small bowl, add besan, cornflour, red chilli powder, turmeric powder, roasted cumin powder, garam masala & salt.
Whisk them well by adding water simultaneously making a thick batter.
Pour this better over potatoes.
Mix them well so that batter is coated to the potatoes. Rest 15 minutes.
After 15 minutes, add potatoes (as much as the basket can accommodate) in greased air fryer basket. You can alternatively deep fry these potatoes till brown and crisp.
Air fry @190°C for 10 minutes initially.
After 10 minutes, brush the potatoes with oil and further air fry for 5 more minutes or until they turn brown and crisp.
Aloo Barule are ready.
