There are two kinds of apples at Costco. Tasty ones, and terrible ones. These were not the best batch. I think they were Gala’s. So I put my trusty mandolin to work and started baking (again). I read that you should use parchment or the apples will stick to the baking sheet, even sprayed, but I used tin foil in absence of parchment and spray and it seemed fine. I baked the first batch, and after cooking for two hours, then watching them all disappear in a matter of minutes, I knew I had to try something more creative to cook more chips at a time- where the wire cooling rack comes in handy. This is less of a recipe and more of a discussion, so I’ll tell you what I did.
- Thinly slice the apples– I used the thinest selection on the mandolin.
- add a layer to each baking sheet- – they shrink up a little so you can overlap them a bit to get more in there…
- sprinkle on cinnamon sugar
- top the baking sheet with a wire cooling rack
- add more slices and sprinkle on the cinnamon sugar (i used up four apples this way)
- Bake at 275 for two hours, flipping each slice after an hour.
- when the apples on the wire racks are done to your liking (chewy or crispy!), remove, then continue baking the ones on the sheets.
