Place the self rising flour into a medium size bowl. Cut the shortening in , using a pastry cutter, or two knives. Add the buttermilk all at once. Gently fold the buttermilk into the flour and shortening, until the dough gathers together, and the flour is mixed in. I use a large wood spoon for this.
Gently cut the biscuits, using a biscuit cutter or glass. Place onto a cookie sheet. Brush the tops of biscuits with melted butter.
Bake for about 15 minutes, or until golden brown on top and bottom.
Makes 9- 2 1/2 inch biscuits. Biscuit yield will depend on size of cutter.
