We live in an area in the world (i.e. France), where electricity can be scarce, especially when we have a storm, when it rains, when there is snow, when the wind blows, when it freezes, and even without an understandable reason. We are not living in La Ville Lumière, sometimes we live in a village of the dark Middle Ages.
That makes that we are particularly touchy about storing too much of our summer harvest in our freezer. Enter the dryer, not hard to make, but hard to beat.
