Mix dry ingredients. In a large bowl, sift together flour, sugar, baking powder, baking soda, and salt. Whisk in the cornmeal until evenly combined.
2 cups all purpose flour , 3 tablespoons sugar, 1 tablespoon baking powder, ½ teaspoon baking soda, 1.5 teaspoons kosher salt, ¾ cup medium grind cornmeal
Work in the butter. Add the cold butter chunks and toss to coat in flour. Using your fingers, press each piece of butter flat into thin sheets, tossing with flour as needed to prevent sticking. Continue until all butter is flattened into thin, flat pieces throughout the flour mixture.
8 tablespoons unsalted butter
Add buttermilk. Pour ¾ cup of the cold buttermilk over the flour mixture. Using your hand in a claw shape, gently fold the ingredients together until a shaggy, loose dough forms. Add more buttermilk 1-2 tablespoons at a time if the dough seems too dry. The dough should be sticky and very shaggy, don't overmix, it will come together!
¾ - 1 cup buttermilk
Shape the dough. Turn the dough onto a floured surface and gently pat it into a rough rectangle about 1-inch thick.
Create the layers (lamination!). Fold the dough in half, then cut it in half lengthwise with a bench scraper. Stack the two pieces on top of each other and press into a rectangle. Turn the dough 90 degrees. Repeat this fold-cut-stack-turn process 2-3 more times (for a total of 3-4 times) to create flaky layers. If dough becomes sticky, refrigerate for 5-10 minutes.
Roll and cut. After the final turn, gently roll the dough to ¾ to 1-inch thickness, and don't go over 1-inch in thickness, or they will topple over while baking! Using a floured 2.5-inch biscuit cutter, press straight down through the dough without twisting. Re-flour the cutter between cuts. Gently press scraps together and cut additional biscuits—you should get 8 total.
Chill. Place biscuits on a parchment-lined baking sheet and freeze for at least 15 minutes.
Bake. Preheat oven to 425°F. Brush biscuit tops with buttermilk or egg wash. Bake for 15-20 minutes until golden brown and the internal temperature reaches 200-205°F. Brush with melted butter or honey butter while warm. S
