Caramelised Apple and Passionfruit Compôte

This recipe is a good all-rounder — try it served on pancakes with ice cream, as a topping on grilled brioche with crème fraîche, or simply with some custard. This will keep in a sealed container in the fridge for 3–4 days but, because of the butter content, it does need to be warmed a little before you serve it.
