Boil Kachalu either in boiling water or roast in air fryer/Otg. It takes 30 minutes in air fryer. For roasting them in air fryer, simply put washed kachalu in the air fryer basket at the highest temperature. Run it for 30 minutes. Insert a knife to check if they are done. If the knife goes easily this means that the kachalu are boiled.
Mix dried mango powder, red chilli powder with roughly 2 cups of water and keep it aside.
When slightly cool, peel off the skin and cut into thin slices.
Now, add all the spices, green chillies, ginger julienne, lemon juice and the dried mango powder plus red chilli powder water.
Toss with light hands using a spatula.
You will see a lot of water at this stage but don't worry, cover it and keep it for few hours. By then, Kachalu will absorb most of the water and you will have yummy spicy Kachalu Chaat.
Remains good for upto a week in the refrigerator. Always keep them covered to avoid drying up.
