Coconut chutney

I made coconut chutney for lunch for K and everyone at his work loved it. He took it with idlis. When I make idlis it always comes out hard. I have tried everything - adding fenugreek seeds, poha, boiled rice but nothing works. Each time, I  gave some excuse or the other - too cold so batter is not fermenting well or boiled rice is not good etc. but I would never admit that I just cannot make soft idlis. K asked me to give up trying but D loves mini idlis so I keep making idlis hoping each time that "this time" the idlis will be perfect. Have not been successful so far. This time I asked Ma to make the batter (secretly hoping that the idlis will turn out hard so my excuses are valid) but what do you know, the idlis came out soft and fluffy! Hmmm, maybe K is right.....

Coconut chutney

1 cup coconut gratings
1-2 green chilis (depending on how spicy you want it)
1" piece ginger
3 tbsps curd
1 sprig curry leaves
mustard seeds
oil
salt, to taste

Grind the coconut, ginger and green chilis with little water to a smooth paste. Empty into a bowl, add curd and salt and mix well. In a small kadai, heat oil. Add mustard seeds. When it splutters, add curry leaves. Add this to the chutney.
