The microwaved apples should be pliable but not completely soft when cooked. To test for doneness, take one apple slice and try to bend it. If it snaps in half, it’s too firm; microwave it for an additional 30 seconds and test again. If Calvados is unavailable, 1 tablespoon of apple brandy or white rum can be substituted.
