Pastry: In food processor, pulse together flour, sugar and salt until combined; pulse in lard until mixture resembles fine crumbs. Pulse in butter, a few cubes at a time, until mixture is in coarse crumbs about the size of large peas. Drizzle in ice water; pulse, adding up to 2 tbsp more ice water, 1 tsp at a time, if needed to form ragged dough.
