A single apple contains 10 per cent to 15 per cent of the daily recommended amount of vitamin C and fibre, two essential nutrients for a healthy diet. While apples are available in the supermarket year-round, they're at their peak in autumn. By drying your favourite apple varieties in the microwave, either off the tree or from the produce bin, you can preserve a fair portion of their vitamin C content and all of the fibre. Drying apples in the microwave is very convenient: It is very quick, and you won't have to purchase a food dehydrator.
Wash the apple and dry it. Slice it as thinly as possible with a sharp knife.
Lay the apple slices out on a paper towel, then cover with another paper towel. Let the paper towels absorb the excess liquid from the apples.
Lay the apple slices on a microwave-safe tray. Place the tray in the microwave.
Set the microwave to defrost, or 30 per cent power. Cook the apple slices at this setting for 10 minutes. Transfer the cooked slices to a plastic container, and leave it open overnight. The next day, seal the container and store.
