Drumstick Gravy - a variation

Tried this last night. It was different from the usual one because we'd run out of onions at home!

What I used:
- 3 Drumsticks cut into 1 inch long pieces
- 2 Potatoes diced into 1 inch cubes
- 2 or 3 Tomatoes
- grated coconut 1 cup
- 1 tsp rasam powder
- an inch of ginger
- Jaggery
- Salt to taste
- Seasoning

Pressure cook the drumsticks and potatoes for 4-5 minutes. In the meanwhile grind together the tomatoes, grated coconut, rasam powder, jaggery and ginger and keep aside. Heat 1 tsp of oil in a pan and prepare the seasoning (mustard seeds, jeera, curry leaves and a pinch of hing). Add the tomato paste and the cooked drumsticks and potatoes, salt to taste and mix well. Bring to 1 or 2 boils and serve hot with rice or rotis.
