Wild-Blueberry and Almond Tartlets

Preparation

1. Step 1

   Make the crust: Pulse almonds in a food processor until finely ground. Add flour, sugar, and salt; pulse to combine. Add butter; pulse until mixture resembles coarse meal. Add yolk and 1 tablespoon ice water; pulse until dough just comes together, adding up to 1 tablespoon more ice water, if needed. Shape dough into a disk, and wrap in plastic. Refrigerate until firm, 1 hour or up to 3 days. (Dough can be frozen up to 1 month; thaw in refrigerator before using.)

   Step 2

   Preheat oven to 375°F. On a lightly floured surface, roll out dough 1/8 inch thick. Cut out twelve 4 1/2-inch rounds. Reroll scraps if necessary. Line twelve 3-or 3 1/4-inch tartlet pans with dough, pressing into bottoms and up sides; trim excess dough flush with rims. Divide shells between 2 rimmed baking sheets. Pierce bottoms of shells all over with a fork. Refrigerate or freeze until firm, about 30 minutes.

   Step 3

   Line shells with parchment. Add pie weights or dried beans. Bake until light golden brown, 20 to 22 minutes. Remove weights and parchment. Transfer to wire racks to cool completely.

   Step 4

   Make the filling: With an electric mixer on medium speed, beat eggs and sugar until pale and thick, about 5 minutes. Using a flexible spatula, fold in flour, ground almonds, and salt.

   Step 5

   With an offset spatula, spread about 1 1/2 teaspoons jam into each shell. Top with blueberries, dividing evenly. Cover fruit in each tart shell with 2 tablespoons batter. Sprinkle batter evenly with sugar and sliced almonds. Bake until tops rise and are golden, 18 to 20 minutes. Transfer to a wire rack to cool completely. Tartlets can be stored in airtight containers at room temperature up to 1 day.
