Having made our own dehydrator, we have successfully made some fruit leather. Started with blackcurrant as these ripened first. Not a difficult decision.

So took some fruit and added some lemon juice. This is to help keep the colour apparently. put that in a saucepan and simmer until soft. Blitz that with a stick blender removing any big lumps. Taste and add honey if you want to. Spread this out thinly on a parchment lined baking tray and whack it in the dehydrator in the sun.

Leave it until it is no longer tacky to touch then remove it. Take it off the parchment, cut it up, roll it into, well, rolls, and put in the fridge.

Great hill food to accompany a sandwich and the internet seems to suggest it will keep for up to a month.

Incidently, we measured the temperature inside the solar dehydrator to be 55 degrees centigrade. Not sure whether that is good or not but it seems to work well.
