3-4 tbsp veg oil
1 tsp black mustard seeds
2 tbsp urad dal
3-4 dried hot red chillies, halved
25 fresh curry leaves
2 medium onions, peeled, quartered & finely sliced
1 tsp salt
1/2 tsp turmeric
1/2 tsp cayenne peppe
1 lb potatoes
1 medium tomato, chopped
pinch asafetida

Heat oil, add mustard seeds, urad dal & chillies. Stir until seeds pop & dal turns red. Add curry leaves. Stir. Add onions. Stir and fry until just brown at edges. Add salt, turmeric, cayenne. Stir 5 seconds. Add tatties. Stir and fry for a minute. Add tomato and asafetida, stir and fry for a minute. Add a little more than 1 cup of water, bring to boil. Cover, turn heat to medium and cook fairly vigorously for about 10 mins, until tatties just tender and water absorbed (ish). Remove cover. Stir and fry on medium low heat for 4-5 mins to get a rich reddish-yellow colour.
