I try never to waste food, but especially right now during the Covid-19 pandemic, it’s not so simple to just go to the store.
I had a bag of apples that the kids just weren’t eating fast enough so I decided to dehydrate them before they went bad (they were already on the soft side).
I used a mandolin slicer (you can get the same one here) to slice the apples thinly. I put them in water with a bit of lemon juice while slicing to keep them from turning brown.

I then spread them out on my dehydrator and turned it on low for about 12 hours. I like to add the chips to muffins and loaves but you could also rehydrate them and turn them into apple sauce. My dog likes to eat them as treats and they’re a lot healthier than some other treat options.
To store, I put them in a mason jar with an oxygen absorber. You could also vacuum seal them but I don’t expect mine to hang around too long as I’m already planning ways to use them.
