I saw that recipe does not have lemon juice.. you NEED lemon juice, just squeeze a bit, to taste, just before serving over your curry. Fingers crossed you have lemons in the house.. Hope you enjoy it! Have you got any yogurt and cucumber, and fresh coriander? It would be very nice to have a simple raita with it. Peel cucumber, discard the wet seedy bit, grate the flesh, add salt and drain in colander. (clove of garlic? if you like) add yogurt and chopped coriander, done.
