the flour with the salt and sugar in a large bowl. Toss half the butter and lard in the flour to coat, then use a pastry blender
or knives or your fingers to cut in the fats until pea sized or a bit smaller. Toss the rest of the butter and lard into the mixture, then cut in again until the mixture resembles coarse meal with some larger chunks of fat throughout.
Use your finger to draw
a trench down the center of the mixture, and sprinkle about 2 tablespoons of the water down the trench and around the outside of the flour. Toss the flour with the water using your fingers or a rubber spatula
. Repeat until the dough comes together in shaggy chunks. Turn the dough onto a lightly floured board and use the heel of your hand to smear pieces of dough away from you. Gather the dough together with a pastry scraper and press into a large disk. Wrap tightly and refrigerate a few hours before using.
On a lightly floured surface, roll the dough just slightly thicker than 1/8-inch. Cut out 5-inch circles, place on parchment on a baking sheet, and chill while you prepare the filling.
