Slice the unpeeled apples very thin, preferably with a bread cutter or mandolin.
Lay the apple slices on a baking sheet lined with parchment paper, dust with confectioner’s sugar, and caramelize in the oven for a few minutes.
Notes / Tips / Wine Advice:
For more delicate, if somewhat more time consuming, apple chips, place the raw apple slices in a vacuum bag with about 21oz (600 g) of simple syrup (see p. 40) and some lemon juice, blanch after 5 minutes, and then chill in ice water. Then take the apple slices out and let dry in the oven for about 8 hours at 120–140 °F (50–60 °C). Turn the chips over halfway through.
You can prepare pear chips using the same recipe.
