Preheat oven to 400 °F and cover baking sheet with parchment paper. Whisk flour, sugar, baking powder, salt and baking soda in large, wide bowl. Using fingertips or a pastry blender, work butter into dry ingredients until the mixture resembles a coarse meal, Add buttermilk and stir until large, craggy clumps form. Reach hands into bowl and knead mixture briefly until it just holds together. To form biscuit rounds: Transfer dough to floured counter and pat out until 1/2 to 3/4-inch thick (err on the thin side if uncertain, as the tall ones will literally rise and then tip over, like mine did the day I photographed these). Using a round cutter (2 inches for regular sized biscuits, 3 inches for the monstrous ones shown above), press straight down — twisting produces less layered sides — and transfer rounds to prepared sheet, spacing two inches apart. To drop biscuits: Drop 1/4-cup spoonfuls onto baking sheet, spacing two inches apart. Both methods:Bake until biscuits are golden brown on top, about 12 to 15 minutes. Cool slightly, then serve warm, with butter/jam/eggs/bacon/sausage and gravy or any combination thereof. Happy weekend! Do ahead: Biscuits are best freshly baked. When I want to plan ahead, I make the biscuit dough and form the individual biscuits, then freeze them until needed. They can be baked directly from the freezer, will just need a couple more minutes baking time.
