Sweet Potato Biscuits

At a friends recommendation, I put this on my list over there on the right. I had some leftover sweet potato in the fridge so I gave these a try yesterday for a snack. 

• 1 cup all-purpose flour
• 3 teaspoons baking powder
• 2 teaspoons white sugar
• 1 teaspoon salt
• 2 tablespoons butter
• 3/4 cup mashed sweet potatoes
• 1/4 cup milk
  
• Preheat the oven to 400 degrees F (200 degrees C).
  In a medium bowl, stir together the flour, baking powder, sugar and salt. Cut in the shortening until pieces of shortening are pea-sized or smaller. Mix in the sweet potatoes, and enough of the milk to make a soft dough.
  Turn dough out onto a floured surface, and roll or pat out to 1/2 inch thickness. Cut into circles using a biscuit cutter or a drinking glass. Place biscuits 1 inch apart onto a greased baking sheet.
  Bake for 12 to 15 minutes in the preheated oven, or until golden brown.
