In our local indian we get a dip to go with poppadoms,sometimes its white,other times its orange,im pretty sure its yoghurt based,but what else do they put into it..thanks.
in most indians you usually get a coconut dip (usually coloured green, red etc), a mango chutney which tastes really sweet, a lime pickle which is pretty hot, a ceramy mint dip (usually white) and a bowl of sliced onions,tomatoes,cucumber etc
The mint dip which is traditionally eaten with very spicy food to cool your pallette. Just get some natural yoghurt, chop up some mint leaves and mix in.
To experiment, you could always add a few drops of lemon/lime juice and some chopped cucumber....even a bit of honey,
