How to Make It
Preheat oven to 450°F. Whisk together all-purpose flour, granulated sugar, baking powder, salt, and baking soda in a medium bowl. Cut cold butter pieces into flour mixture with a pastry blender until mixture is crumbly. Make a well in center of mixture. Add whole buttermilk, and stir until mixture comes together in a ball.
Scrape dough onto a lightly floured surface, and knead three to four times. Lightly flour top of dough and a rolling pin. Roll dough into a rectangle, and fold dough in half so short ends meet. Repeat the rolling and folding procedures one more time.
Roll dough to 1⁄2-inch thickness. Cut with a floured 2-inch round cutter, rerolling scraps once. (You should have 10 biscuits.) Place biscuits 1 inch apart on a baking sheet lined with parchment paper. Bake in preheated oven until golden brown and firm to the touch, about 10 minutes.
Brush tops of hot biscuits with melted butter, and serve with sliced ham and choice of Biscuit Spreads.
