Mor Kuzhambu - A dish from Tamil nadu, easy to prepare. I came across this recipe in Prema's Cook book and found the Kuzhambu very tasty.
 

Ingredients:   Thick buttermilk/curd- 4 cups Rice- 1tsp Channa dal- 1 tsp Toor dal- 1 tsp Turmeric powder- 1/4 tsp Green chillies- 4 Ginger- a small piece Garlic- 2 to 3 cloves Coconut grated-3 - 4tsp Salt to taste Any veggies chopped - 1/2 cup (like pumpkin, okra, ash gourd, cucumber, carrot, beans, potato. Add any one or two vegetables of your choice.) For Tempering: Coconut oil/cooking oil- 1 tbsp Mustard seeds- 1/4 tsp Red chillies- 1 curry leaves- a few pearl onions- 3 chopped finely Asafoetida- a pinch

Method:

Soak rice, and the dals together for 15 to 20 minutes.
 

Whisk/beat the buttermilk/curd with turmeric powder and keep aside.
 

Grind green chillies, ginger, garlic, coconut with the soaked rice and dal to a fine paste.
 

In a pan add 1/2 cup of water and the veggies and cook the for some time.
 

When they are half cooked add the ground paste and salt to it.
 

Simmer the flame and add little water to it so that the veggies are cooked fully and the raw smell of the paste disappears.
 

Add the buttermilk/ curd to it.
 

Heat coconut oil/cooking oil in a frying pan and add the ingredients for tempering one by one and fry for a minute.
 

Finally pour that to the curd mixture. Morkuzhambu is ready to be served with rice.
