Every household has their own recipe, this one according to me is the easiest and also quick to make.
Potato, boiled - 5 medium
Tomato, pureed - 1 medium
Onion - 1 medium
Ginger - 1 inch piece
Green chillies - 2
Whole cumin seeds - 1/2 teaspoon
Asafoetida - 1/4 th teaspoon

Cumin powder - 1 teaspoon
Red chilli powder - 1 teaspoon
Garam masala powder - 1/2 teaspoon
Mustard Oil - 3 tablespoon
Fresh grreen coriander, chopped - 3-4 tablespoon
Peal and and cut the boiled potatoes into quarters.
Grind the onion and ginger into a fine paste. To this paste add red chilli powder, turmeric powder and cumin powder and keep aside.
Heat 1 tablespoon of Mustard oil in a kadhai and saute the potatoes on medium flame till lightly brown. Drain and keep aside.
Heat the remaining oil in the same kadhai used to saute the potatoes, add whole cumin seed, one it starts releasing the aroma add the asafoetida, followed by the onion and ginger and masala paste. Fry for 3-4 minutes.
Add the sauteed potatoes and mix well, add a cup of water, bring it to a boil, add the garam masala powder,broken green chillies. Mix well and cook.
Once the curry comes to a boil add the chopped coriander mix well, reduce the heat cover and cook until it is left with a thick gravy.
