Ingredients:
- 3 large firm apples (approx. 450g), such as Honeycrisp or Fuji
- 1.5 teaspoons ground cinnamon (approx. 4g)
- 1 pinch sea salt (optional)
Instructions:
- Position oven racks in the upper and lower thirds of your oven. Preheat oven to 200°F (95°C). Line two large baking sheets with parchment paper or silicone mats.
- Using a mandoline slicer set to 1/16-inch or a very sharp chef's knife, slice the apples into paper-thin rounds. Remove any stray seeds, but the core can remain for a star pattern.
- Arrange the apple slices on the prepared baking sheets in a single layer. Ensure slices do not overlap, though they may touch slightly as they will shrink during baking.
- Load a small sifter with ground cinnamon and lightly dust the tops of the apple slices from a height to ensure an even coating.
- Place sheets in the oven and bake for 1 hour. Remove from oven, flip each slice, and rotate the baking sheets between the upper and lower racks.
- Bake for another 1 to 1.5 hours. The chips are ready when the edges are curled and they feel dry to the touch, though they may remain slightly flexible until cooled.
- Remove from the oven and let the chips sit on the baking sheet for 10-15 minutes. This cooling phase is essential for the chips to fully crisp up.
