In a bowl add in order the flour, grated butter, then buttermilk.

Turn the mixture out onto a floured surface and pat down to about 3/4-inch (2cm) thickness.
Cut into your preferred sized biscuits. This can be done with a cookie cutter, can, or cup may be used among other things. Tip: Push directly down when cutting out the biscuits, if the cutter is twisted they do not rise as much.
