Preheat oven to 350 degrees.
Combine the dry ingredients (flour, baking powder, salt and baking soda) in a bowl. Chop the butter into 1 inch pieces. Place the butter pieces in a food processor with the dry mix and pulse until it resembles pea-sized crumbles.
Transfer the mixture into a large mixing bowl. Add the buttermilk and gently fold until a tender dough develops, taking care not to over mix. Add more buttermilk if necessary to get a slightly rough, yet delicate dough. Let rest for a couple minutes before rolling.
Transfer the biscuit dough onto a floured surface and roll it out until it’s about 1 inch thick. Fold dough in half one time, and gently roll again until it reaches 1½ inches thick.
Using a biscuit cutter that is about 3 inches in diameter, cut the biscuits and place them on a parchment paper-lined baking sheet. Bake at 350 ̊for 20 minutes, or until the tops are very lightly browned. Allow biscuits to cool for 20 minutes before serving.
