2. Stir the tomatoes, purée and potatoes in with the beef with some seasoning and heat through. Smooth the surface of the beef mixture with the back of a spoon, then slice the cooked aubergine and arrange on top. Pour the yogurt mixture over the aubergines, smooth out evenly, then grill until the topping has set and turned golden.

Cooking notes

When scaling protein-led dishes, weigh the meat rather than counting pieces, and remember that the pan size limits how much you can sear at once.

For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.

When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
