Only two ingredients—lemon and milk—are what it takes to make paneer at home. It’s an experiment worth trying (it certainly feels like conducting a chemistry experiment), both for a sense of achievement and for unrivaled freshness. Yotam has published a recipe for it in the Guardian newspaper, but many others are also available online. If you buy your paneer—which makes the most satisfying filling for the grilled eggplants here, as it soaks up the coconut sauce—try to find a soft variety, which has a texture like compressed ricotta. Other varieties, which are harder and slightly rubbery, are more suitable for making vegetarian tikka kebabs, but they will also do if that’s what you’ve got. For a vegan option, use extra-firm tofu. Try to get a good-quality, chunky Indian mango pickle for this.
Both the eggplant slices and the lentil sauce can be prepared the day before, if you want to get ahead. In fact, you can make the whole dish a day ahead, up until before it goes into the oven, then chill in the fridge and just bring to room temperature before warming up.
The coconut dal is a great recipe in its own right. Double it, if you like, and serve with our curry-crusted rutabaga steaks and some rice.
