Kosimbir- with green mangoes

Kosimbir was often made at my place, and come summer and I start making it for myself. This is a slight variation on the old favourite, with green mango slices for the sour taste.

1 cup split moong dal
1 cucumber
1/2 green mango
salt to taste

For tempering (optional)
1 tsp mustard seeds
1 green chilli
1 sprig curry leaves
a little cooking oil


Method
Soak the split moong dal overnight (or at least for 4 hours)
Cut the cucumber and the mango into tiny pieces and mix well with the dal
Add salt to taste, and mix well
If you like, you can make the tempering and pour it over the kosimbir, or you can avoid it with no change in taste.
Serve chilled, either as a stand alone snack, or with rotis.
