Apple-and-Black-Walnut-Frangipani Tart

• 1 3/4 cups flour
• 1/4 cup sugar
• 1/4 teaspoon salt
• 7 tablespoons cold unsalted butter, diced
• 1 large egg, beaten
• 1 1/2 cups black-walnut frangipani
• 5 apples, preferably tart ones like Granny Smiths or Crispins
• 2 tablespoons granulated sugar
• 3/4 teaspoon ground cinnamon
• 13 cup apple jelly
• 6 tablespoons ground walnuts
• Powdered sugar

1. To make the dough, put the flour, sugar and salt in a food processor and pulse to combine.
2. Add the butter and pulse until the mixture resembles coarse meal.
3. Add the egg and pulse until the dough begins to pull away from the sides of the bowl.
4. (Add water a teaspoon at a time if the dough seems too dry.)
5. Wrap the dough in plastic wrap and refrigerate for 1 hour.
6. On a lightly floured surface, roll the dough into a circle about 12 inches in diameter and ease it into a 10-inch tart pan.
7. Trim the edges.
8. Refrigerate for at least 30 minutes.
9. Preheat the oven to 325 degrees.
10. Spread the chilled crust with the frangipani.
11. Peel, halve, core and thinly slice the apples.
12. Fan the apples over the frangipani.
13. Combine the sugar and the cinnamon in a small cup, mix well and sprinkle over the apples.
14. Bake until the crust is browned and the apples are soft, about 40 to 50 minutes.
15. Remove from the oven and cool.
16. Remove the tart from the pan.
17. Warm the apple jelly in a small saucepan over low heat until it is just melted.
18. Brush the hot jelly over the surface of the tart.
19. Brush the crust with jelly and dust the crust with ground walnuts.
20. Dust the crust again with powdered sugar.
21. Slice and serve.
