Strawberry Shortcakes with Mint and Whipped Cream

Preheat oven to 375 °F. Line baking sheet with parchment paper. Blend flour, 4 tablespoons sugar, baking powder, and salt in processor 5 seconds. Add butter. Using on/off turns, process until mixture resembles coarse meal. Add 1 cup cream and orange peel. Process just until moist clumps form. Gather dough into ball; gently knead 5 turns. Roll out dough on floured surface to 3/4-inch-thick round. Using 3-inch-diameter cutter, cut out 3 rounds. Gather dough and reroll as needed to make 3 more 3-inch rounds. Arrange rounds on prepared sheet. Brush with 2 tablespoons cream; sprinkle with 1 tablespoon sugar. Bake biscuits until pale golden and tester inserted into center comes out clean, about 20 minutes. Cool 15 minutes. (Can be made 2 hours ahead.)
