Three components here, I know, but they’re all quick and simple to do, can all be made well in advance, and there’s no work to do on the day apart from some pretty informal assembly. The cheesecake (which keeps for 3 days) and compote (which keeps for 5 days) need to be kept in the fridge, and the crumble (which keeps a good week or so) just needs to be kept in an airtight container at room temperature. The compote and crumble are also lovely for breakfast, if you have any left over or want to make more, served with Greek yoghurt.
