Sweet Potato Biscuits
  1. Peel the sweet potato. Cut into chunks, then boil until tender. Drain.
  2. Place a rack in the center of the oven and preheat to 425ยบ F.
  3. Lightly grease a baking sheet with butter, cooking spray or use a Silpat mat.
  4. In a small bowl, mash together the sweet potato and 1/3 cup milk. Measure 1 cup of the mixture and set aside.
  5. In a large bowl, whisk together the flour, sugar, baking powder, and salt. Cut in the butter with a pastry blender or two knives until the mixture resembles a coarse meal. Add the sweet potato mixture and fold gently to combine. If the mixture is too dry, add more milk a little at a time until all the flour is moistened. If it is too moist, add a little more flour.
  6. Sprinkle a small handful of flour on a work surface. Turn the dough out onto the surface and knead lightly 2 to 3 times with the palm of your hand until the mixture comes together. Pat the dough out into a 1/2-inch-thick round.
  7. Using a 2 1/2-inch-round biscuit cutter, cut the dough into biscuits. Gently reroll the scraps and cut out more biscuits. Place the biscuits on the prepared baking sheet and bake until light golden brown and firm to the touch, 12 to 14 minutes.
