Jam Tarts

Combine flour, shortening, sugar, and salt in the bowl of a food processor; pulse until the mixture resembles coarse crumbs. Add water; process until it forms a dough ball. Wrap dough ball in plastic wrap; refrigerate until well chilled, at least 30 minutes.

Preheat the oven to 400 degrees F (200 degrees C). Grease two 12-cup shallow muffin tins.

Roll dough out until thin; cut into rounds with a cookie cutter. Place each round in a muffin cup. Add 2 teaspoons jam to each cup.

Bake in the preheated oven until golden brown, about 20 minutes. Cool tarts on a wire rack.
