Puli Gozzo 

(South Indian Eggplant Sauce)

This was from Julie Sahni's Classic Indian Vegetarian and Grain Cooking. Aside from the eggplant, it also contains onions, tomatoes, and spices including mustard seeds and sambhar powder. I left out the curry leaves, coconut, and tamarind. I'd made Gozzo, a simpler sauce with mustard seeds, onions, and tomatoes, several times before, but never this variation. The pic is from last month, and has been waiting for its turn. This sauce was a nice change from the usual.
