1 stick frozen butter
2 ½ cups of all purpose flour
¾ teaspoon salt
4 teaspoons baking powder
1 cup chilled butter milk
Preheat oven to 475 degrees. Grate frozen butter using large holes of a box grater. Whisk together flour, salt and baking powder. Then sift this mixture.
Toss together grated butter and flour mixture in a medium bowl. Stick back in the freezer for 10 minutes.
Turn dough out onto a lightly floured surface. Lightly sprinkle flour over top of dough. Using a lightly floured rolling pin, roll dough into a 3/4-inch-thick rectangle (about 9 x 5 inches). Fold dough in half so short ends meet. Repeat rolling and folding process 4 more times.
