All the various components of this dish can be prepared a day in advance, if you want to get ahead. Keep all the elements separate and in the fridge, bringing everything back to room temperature before you assemble the dish. When you next see some fresh curry leaves, grab hold of them – they are sometimes around but then they disappear from the shelves for a while. Freeze what you don’t use so that they’re ready for when you next need them. Lightly fried in
