Buttermilk Biscuits

I got this recipe from Elizabeth. The notes within the recipe are hers, not mine. OMG! These are evil. I already have eaten 2!
Thank God I didn't have sausage gravy to go with!

They are really easy to make. I got 10 out of the dough.

Buttermilk Biscuits
by Alton Brown, makes 10-12 if you use a 2 inch cutter

2 cups flour
4 teaspoons baking powder
1/4 teaspoon baking soda
3/4 teaspoon salt
2 tablespoons butter
2 tablespoons shortening
1 cup buttermilk, chilled

Preheat oven to 450 degrees.In a large mixing bowl, combine flour, baking powder, baking soda and salt. Using your fingertips, rub butter and shortening into dry ingredients until mixture looks like crumbs. (Alton says: the faster the better, you don't want the fats to melt. I say: use a pastry cutter if you want, and make sure the bowl is cold, too.) Make a well in the center and pour in the chilled buttermilk. Stir just until the dough comes together. The dough will be very sticky.

Turn dough onto floured surface, dust top with flour and gently fold dough over on itself 5 or 6 times. Press into a 1-inch thick round. Cut out biscuits with a 2-inch cutter, being sure to push straight down through the dough. Place biscuits on baking sheet so that they just touch. Reform scrap dough, working it as little as possible and continue cutting. (Biscuits from the second pass won't be as tall, but they'll still be biscuits, so whatever. I actually reworked my scrap scraps twice and got a single, fairly flat biscuit out of the last pass.)Bake until biscuits are tall and light gold on top, 15 to 20 minutes. Best served hot, but reheat ok in a toaster oven.
