Ingredients

1 lb. Potato or kadachakka (bread fruit), cut into small cubes
1/2 tsp. chile powder
1/4 tsp. turmeric powder
2 tsp. coriander powder
1 tsp. garam masala
3 oz. coconut milk (optional)
1/3 onion, cut into small pieces
2 green chile (optional), cut long
oil, salt, mustard seeds
Curry leaves (optional)

Method

Heat oil, fry mustard seeds, add onion, green chile & curry leaves, stir until
it turns light brown. Then add salt, all the powders and masala, stir until it
turns brown, then add coconut milk and veg., stir well, cover it and cook until
well cooked. (If not adding coconut milk, add a cup of water instead). It is
ready to serve! (In fact, it should be made by roasting coconut and all the
spices, and blending them very nicely, but it is not easy to do it here. So I
made up this version.) (You can cook kadala too the same way. For kadala,
you can use just the garam masala and chile powder only. Either way, it tastes
good.)
