Apples - Simple & Dry Apple Simple Syrup: Take equal parts of a good apple cider and sugar and mix them until they combine. Dried Apple Chips: Slice an apple thinly with a mandolin or sharp knife. Place on a drying rack in the middle of a 175ºF oven. Baking time will depend on the width of the slices, but there should be just a little pliability to them that will dry out as they cool. Let them cool on the rack but pull them loose while still pliable or they’ll stick to the rack.
