The dahl I took away was actually 2 different ones made separately as experimental, and then finally combined. The first was red lentil with mild spice and coconut milk (quite nice) and the second was a 4 lentil mix which my wife said was a bit dry or floury. I allowed both to sit in the fridge for 24 hours before tasting again and deciding to combine them, which gave a nicer dish than either alone.
My next attempt will be to make the dhansak lentil / dhal base without any meat and muck about with that. What I did find when searching for recipes is that they are all very similar, so the next thing to do would be to search for something that is obviously different in one way or another.
I agree with Santa as well. Several of the recipes I found were indeed very watery / soup like. This isn't what I was after for my trip away though.
