Preheat oven to 425*
Butter 8-9 inch round cake pan or cast iron skillet.
In a large mixing bowl, stir together the self-rising flour, sugar, and salt. Work the shortening in with your fingers until there are no large lumps.
Gently stir in the cream, then some of the buttermilk until dough resembles wet cottage cheese. It should be a wet mess -- not soup, but cottage-cheese texture. If you are not using a low-protein flour, this may take considerably more than 1 cup of buttermilk.
Spread the plain all-purpose flour (not self-rising) out on a plate or pie pan. With a medium (about 2 inches, #30) ice cream scoop or spoon, place three or four scoops of dough well apart in the flour. Sprinkle flour over each. Flour your hands. Turn a dough ball in the flour to coat, pick it up, and gently shape it into a round, shaking off the excess flour as you work. Place this biscuit in the prepared pan. Coat each dough ball in the same way and place each shaped biscuit scrunched up against its neighbor so that the biscuits rise up and don't spread out. Continue scooping and shaping until all dough is used.
Place the pan on the arranged shelf in the oven. Bake until lightly browned, 20 to 25 minutes. Brush with the melted butter. Invert onto one plate, then back onto another. With a knife or spatula, cut quickly between biscuits to make them easy to remove. Serve immediately. "Butter 'em while they're hot."
**Do not use self-rising flour for shaping, as the leavener will give a bitter taste to the outside of the biscuits.
**I prepared dough as above but since I wanted large biscuits, I patted out the dough on a floured pastry mat, then cut using a large round biscuit cutter.
To prepare shortcake, slice biscuit in half, top with a mound of fresh sweetened berries, a big spoonful of sweet whipped cream, and a zest of Hershey's Dark Chocolate.
