This nutty shortcrust pastry becomes the perfect base for our favorite Blueberry Jam Tartlets.
Finely grind almonds in a food processor. 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 water if needed.
Shape pastry into a disk, and wrap in plastic. Refrigerate at least 30 minutes (up to 3 days) before rolling.
Pastry can be frozen up to 1 month.
