Tambli's with yogurt were not featured much at my mom's place since I and my bro both did not like yogurt. If you do not like it you can even replace it with little tamarind. The one that I am mentioning here is Hinga tambli.
Here is what's needed:
1 cup grated Coconut
2 - 3 tbsp Yogurt (increase as per your taste)
2 green Chilli's slit
a generous pinch of Asafoetida/Hing
Salt to taste
1) Heat Oil and fry the green Chilli's until they change their colour to light green. Take care while frying as they tend to splutter. Add in the Asafoetida and remove from flame. Add this to grated Coconut.
2) Beat the Yogurt and whisk with little water.
3) Grind grated Coconut + green Chilli's + Asafoetida along with yoghurt and Salt to a smooth paste. Add water if desired to bring it to desired consisitency. Serve cold with rice and some side dish.
