For the mincemeat pies, substitute eight tablespoons cold lard for eight tablespoons of the butter.
Pulse flour, sugar, and salt in a food processor to combine. Add butter; process until mixture resembles coarse meal, about 10 seconds. With machine running, add ice water in a slow, steady stream through feed tube until dough just comes together (no longer than 30 seconds).
Turn out onto a work surface. Divide in half. Shape into disks. Wrap in plastic. Refrigerate at least 1 hour (up to 2 days).
Pate Brisee Walnut Variation: Make recipe as directed, substituting 3/4 cup ground walnuts for 3/4 cup flour.
