Pretty sure this if from Indian Epicure: Classic Recipes from North India by Meera Taneja, but my cat isn’t letting me up to check.
Ingredients:
2 large round aubergines
1/2 lb onions
1 inch root ginger, chopped fine
1t cumin seed
1t salt
1/2t chilli powder
1 green chilli, chopped fine
1lb fresh or canned tomatoes
2-3T oil
Scorch the aubergines under the grill until the skin has charred. Set aside to cool. Peel off the charred skin and chop the aubergines. Chop the onions finely, heat the oil in a deep frying pan, add the onions, green chilli, ginger, cumin seeds and chilli powder and fry until the onions are light brown. Add the aubergines and tomatoes. Cook slowly, stirring frequently. The aubergines will absorb the oil from the onions, so cook until the aubergine, tomato and onion mixture releases the oil slightly – about 15 minutes. Serve very hot. [also good with some yogurt mixed in at the very end.]
