An authentic Indian specialty cooked with freshly ground roasted spices, caramelised onions, and aromatic herbs in the traditional style.
Heat the mustard oil until it smokes lightly, then fry the potatoes until golden on all sides and set aside.
Lower the heat, add the asafoetida, fennel powder, ginger powder, and chili powder, and fry for 30 seconds with a splash of water.
Take the pan off the heat and stir in the whisked yogurt a little at a time so it does not split.
Return the potatoes to the pan, add the salt, cover, and cook on the lowest flame for 12 minutes until the gravy thickens.
Garnish with coriander leaves and serve with poori or naan.
