Has to be lamb for me, though often I have to settle for chicken. Cooking the dhal in stock really adds something for me. Plenty of garlic and green chilli too, with a tarka of more garlic and green chilli. I used to use the dhal recipe with CAs dansak recipe, but now I just spice it as I fancy. I use pinapple juice and fresh lemon, but I'll have to try the marmalade idea for a change.
