Step 2: In a bowl whisk together the flour with the other dry ingredients (- baking soda) and freeze the dry ingredients for 30 minutes.

Step 3: Scrape the frozen butter into the dry ingredients and toss. Pour in the buttermilk and stir until you have a stiff dough.

Step 4: Scrape dough onto a floured board and work the dough into a 10 x 7 inch rectangle. Fold the rectangle into thirds and rotate 90 degrees. Using a rolling pin flatten the dough into a 10 x 7 inch rectangle. Repeat the folding, turning and rolling process 3 times, ending with the dough shaped into a 12 x 10 inch rectangle that is 1/2 inch thick. Trim edges and then cut into 12 equal squares. Space the biscuits at least 3 inches apart on a parchment lined baking sheets and freeze for 2 hours or up to 3 days.
