Sweet Potato or Pumpkin Biscuits
A cup of mashed sweet potatoes or pumpkin guarantees a soft biscuit. The gluten just can’t get all worked up, so to speak. They take a little longer to bake than a regular biscuit, but you get a better yield. Once you've mastered how to use the shortening or lard, substitute butter for a very special biscuit.
You may also want to try a savory variation. Omit the optional spices, or add ½ cup of crumbled, cooked bacon before adding the sweet potatoes.
For the biscuits:
- 2 ¼ cups self-rising flour
- ¼ teaspoon ground cinnamon (optional)
- ¼ teaspoon ground nutmeg (optional)
- 1/3 cup chilled shortening or lard, roughly cut into ½-inch pieces
- 1 cup mashed sweet potatoes or pumpkin purée
- ¼ cup milk (optional)
For the icing:
- ½ cup confectioners’ sugar
- 2 tablespoons buttermilk or milk
For the biscuits:
Preheat the oven to 450 degrees.
Fork-sift or whisk 2 cups of flour, cinnamon, and nutmeg in a large bowl, preferably wider than it is deep, and set aside the remaining ¼ cup of flour. Scatter lard over the flour and work in by rubbing your fingers with the lard and flour as if snapping your thumb and fingers together (or use two forks or knives, or a pastry cutter) until the mixture looks like well-crumbled feta cheese, with no piece larger than a pea.
Shake the bowl occasionally to allow the larger pieces of fat to bounce to the top of the flour, revealing the largest lumps that still need rubbing. If this method takes longer than 5 minutes, place the bowl in the refrigerator for 5 minutes to re-chill the fat.
Make a deep hollow in the center of the flour with the back of your hand. Scoop the sweet potatoes (or pumpkin purée) into the hollow and stir with a rubber spatula or large metal spoon, using broad circular strokes to quickly pull the flour into the sweet potatoes.
Mix just until the dry ingredients are moistened and the sticky dough begins to pull away from the sides of the bowl. If too dry, add 1-4 tablespoons of milk.
Lightly sprinkle a board or other clean surface with some of the reserved flour. Turn the dough out onto the board and sprinkle the top lightly with flour. With floured hands, fold the dough in half, and pat dough out into a 1⁄3 to ½ inch-thick round, using a little additional flour only if needed. Flour again if necessary, and fold the dough in half a second time.
If the dough is still clumpy, pat and fold a third time. Pat dough out into a ½-inch thick round for a normal biscuit, ¾-inch thick for a tall biscuit, and 1-inch thick for a giant biscuit. Brush off any visible flour from the top. For each biscuit, dip a 2-inch biscuit cutter into the reserved flour and cut out the biscuits, starting at the outside edge and cutting very close together, being careful not to twist the cutter. The scraps may be combined to make additional biscuits, although these scraps make tougher biscuits.
Using a metal spatula if necessary, move the biscuits to the pan or baking sheet.* Bake the biscuits on the top rack of the oven for a total of 12-14 minutes, depending on thickness, until light golden brown.
After 6 minutes, rotate the pan in the oven so that the front of the pan is now turned to the back, and check to see if the bottoms are browning too quickly. If so, slide another baking pan underneath to add insulation and retard browning. Continue baking another 6-8 minutes until the biscuits are light golden brown.
For the icing:
Meanwhile, whisk the confectioners’ sugar and milk (or buttermilk) until smooth to make an icing. When the biscuits are done, remove from oven and slide them onto a rack over a piece of waxed paper. Drizzle the icing over the warm biscuits. Discard the paper with the excess icing.
Serve hot right away.
