2 cups unbleached all-purpose flour
2/3 cup confectioners’ sugar
1 teaspoon baking powder
1/4 teaspoon fine salt
Grated zest of 1 lemon or 1 small orange—or a little of both (about 1 tablespoon)
1 stick plus 3 tablespoons (11 tablespoons total) cold unsalted butter, cut into 1/2-inch cubes
1 large egg
1 large egg yolk
Put the flour, sugar, baking powder, salt, and zest in the work bowl of a food processor fitted with a metal blade. Pulse briefly to combine. Distribute the butter around the bowl and pulse until the mixture is crumbly. Add the egg and egg yolk and process until the dough begins to clump together.
Turn the dough out onto a clean work surface and gather it together into a ball. Form the dough into two disks, one slightly larger than the other. Wrap each disk tightly in reusable or plastic wrap and refrigerate for at least 1 hour, or until well chilled (overnight is fine). Remove the dough from the refrigerator for about 30 minutes before rolling it out
Frangipane layer:
6 tablespoons (85g) unsalted butter, at room temperature1/2 cup (99g) granulated sugar
1/4 teaspoon table salt
1 cup (96g) Almond flour
3 tablespoons (23g) all-purpose flour
1 large egg, at room temperature
2 teaspoons almond extract
In a medium bowl or the bowl of a stand mixer, beat together the butter, sugar, and salt until pale and fluffy, about 1 minute on medium speed.
Stir in the two flours, egg, and almond flavoring. Mix until just combined.
Apple Layer:
3 to 4 tart firm apples I like Honeycrisp or Granny SmithAssemble the Tart:
Make the crust, blind bake, and cool as described above. Then lower the oven to 350 degrees.
Prepare the frangipane filling and spread it into the cooled crust.
Place the sliced apples over the frangipane filling in a circular design overlapping to fill the entire top of the tart pan. Sprinkle sugar over the apples.
Place tart in a 350-degree oven and bake until apples are soft and edges are slightly browned -- 45 minutes to an hour.
Remove and allow the tart to cool. Shake powdered sugar on top or brush with heated apricot jam for a glazed appearance.
Store the tart in the refrigerator between servings.
