We will use boiled potatoes, peel and chop them into cubes.
Now heat ghee in a kadhai or wok and add cumin seeds. Let splutter. Add green chilly, ground coriander seeds and a large pinch of asafoetida. Saute the spices for a few seconds.
Now add chilly powder, turmeric powder, coriander powder, dry mango powder, black pepper and salt to taste. Give a quick mix, and add a tablespoon of water.
Increase the flame and add the cubed potatoes. Mix well so the potatoes are well coated with spices.
Finally cover and cook on slow flame for 3-5 minutes.
Garnish with coriander leaves.
