I love Paul Red or Ida Red apples for dumplings
Firm-fleshed baking apples like Rome Beauty or Ida Red perform best in wrapped pastries because their cellular walls hold structure during high-heat baking rather than collapsing into applesauce. Selecting fruit of uniform size ensures even cooking throughout the pastry casing.
Assembling these pastries ahead of time streamlines holiday hosting. Assemble the unbaked dumplings completely, transfer them to a parchment-lined baking sheet, and freeze them solid for three hours before wrapping individually in plastic wrap and foil. Frozen unbaked dumplings keep for up to two months in standard freezer conditions. Bake them straight from the freezer by adding 15 minutes to the initial 425 degree Fahrenheit oven duration. Pour the boiling sugar syrup around the base just before sliding the pan into the oven so the pastry crisps while the core softens.
Rolling pastry to an even thickness of one-eighth of an inch prevents dough tears when enclosing the fruit. Seal the four corners tightly over the top of the apple to trap steam inside, which cooks the fruit from the inside out. Cool finished dumplings on a wire rack for 20 minutes before serving to let the internal syrup thicken slightly.
