I saved more fruit that I know I will get round to eating, especially cycling in the heat where it'll get bashed about and horrible, so I stewed it up so I can eat it more flexibly. Toast, muesli topping, as a snack, a desert, ... And stores neatly in a bottle.
It's also one of the advantages of cooking with wood, there is a plentiful supply of it. Would have never done this when I used gas to cook on.
