Buttery, flaky, quick—this dough has it all. See cooks' note, if you need to halve the recipe to make the plum-blackberry streusel pie .
Cooks' notes:
•Dough can be chilled up to 1 day. Let stand at room temperature 20 minutes before rolling out.
•Recipe can be halved if making a single-crust pie. Use a rounded 1/4 teaspoon salt and start with 3 tablespoons water.
•If making both pies in this menu, make 2 separate batches of dough.
