Majjiga Pulusu (Buttermilk stew)

My mother in law makes excellent Majjiga pulusu, she doesn't use the Channa dal or besan in her version.
Here is my version of it.

Ingredients:

1 cup cubed vegetables (boiled)(lady finger,drumstick, tomato,bottle guard)
3 Cups sour buttermilk
1/4 tsp turmeric powder
1 cup water
Salt to taste
2 tbsp Besan

Grind to paste:

4 green chillies
1 inch piece ginger
1 tsp coriander seeds
1 tsp cumin seeds
3 tbsp grated coconut

for the seasoning

1/2 tsp Mustard seeds
1/4 tsp hing
1/2 tsp cumin seeds
1 tsp oil
8-10 curry leaves
2 red chillies

Method:

Take the buttermilk in a bowl add water and mix well.Add besan , turmeric powder , ground chilli paste and mix well.
Place in on the stove and bring to boil, simmer it and add the boiled vegetables , salt and mix well.Cook it on low flame till vegetables absorb the flavours.
Heat oil in another pan and when the oil is hot add the mustard seeds, cumin seeds, hing, red chillies, curry leaves and when they start crackling add it to the stew.
Garnish with coriander leaves and serve hot with rice.
