Originally from a Madhur Jaffrey recipe, this has become a firm family favourite. Vegetarian food can sometimes become "samey" but the way the aubergine dissolves and creates its own sauce makes this simple but spicey dish really special. Serve with white rice with 2 tbs of graated coconut toasted and sprinkled on top. To dress it up for a meal-for-two treat or dinner party, serve with naan bread and yoghurt sauce (recipes included). The rule with the potato and aubergine is, to use about the same volume (not weight as potatoes are heavier) of both.
