2 cups self-rising flour
¼ cup very cold butter, cut into pats, plus additional for brushing
⅔ – ¾ cup very cold buttermilk
Preheat the oven to 425°F. Spray an 8-inch or 9-inch round pan with a light coat of cooking spray and set aside.
Place flour in a large bowl. Use a pastry cutter or forks to work the butter into the flour until the lumps are about the size of large peas. Alternatively, you can freeze the butter and use the large holes on a box grater to grate the butter into the flour. Then use your hands to make sure that the flour pieces are coated with flour.
Add ⅔ cup of buttermilk to the flour mixture. Use a wooden spoon or spatula to stir until a soft dough forms. It should hold together when pressed, but shouldn't be too wet. Add small amounts of additional buttermilk slowly, as needed, until dough is SLIGHTLY sticky.
Turn the dough out onto a lightly floured surface. Knead for about 1 minute (folding the dough back over on itself), adding flour to the counter and your hands, as necessary, to prevent sticking.
Pat the dough to ¾-inch thickness. Use a biscuit cutter to cut out the individual biscuits. Firmly press the cutter down into the dough, but do not twist. (Twisting the biscuit cutter seals off the edges of the biscuits and they therefore will not rise as high.)
Roll out the dough once or twice more to use up the remaining dough scraps.
Arrange the biscuits in the prepared pan. At this point, the dough will be a bit warmer from working with it, so I like to place the pan of biscuits in the freezer for about 10-15 minutes to chill again.
Just before you put the biscuits in the oven, brush the tops with melted butter.
Bake for 14 -15 minutes, or until the biscuits are a light golden brown on top. Brush the tops of the biscuits with additional melted butter when they come out of the oven; serve warm.
