01 - In a large mixing bowl, whisk together the all-purpose flour, fine sea salt, and optional dried herbs and black pepper.
02 - Add cold unsalted butter cubes and cut them into the flour mixture using a pastry blender or fingertips until it resembles coarse crumbs with some pea-sized pieces.
03 - Stir in the egg yolk and 2 tablespoons of ice water, mixing gently with a fork until the dough begins to hold together. Add additional ice water a few drops at a time if necessary.
04 - Turn dough onto a lightly floured surface, knead briefly until smooth, flatten into a disk, wrap in plastic wrap, and refrigerate for 30 minutes.
05 - Preheat oven to 375°F (190°C). Roll chilled dough to approximately 1/8 inch (3 mm) thickness on a floured surface.
06 - Cut dough into circles and gently press into tartlet pans or a large tart pan, trimming any excess dough.
07 - Prick the bases of the shells with a fork, line each with parchment paper, and fill with baking beans or pie weights. Bake for 15 minutes.
08 - Remove parchment and weights, then bake an additional 5 to 7 minutes until the shells are golden and crisp.
09 - Allow tart shells to cool completely on a wire rack before filling with desired savory fillings.
