1. Idli batter can be stored in the refrigerator for 4-5 days.
2. Coconut chutney can be stored in the refrigerator for a couple of days or more if in the freezer without adding salt or tempering.
3. Chutney goes extremely well with idli, dosa, uttapam, masala paniyaram,upma, vada. I like it with steamed rice too.
