Daily Bread: Sweet Potato Biscuits

A big hit at a brunch we hosted recently - Sweet Potato Biscuits:

1 large sweet potato
1 1/2 cups all-purpose flour
2 teaspoons baking powder
1/4 teaspoon salt
1/2 teaspoon ground cinnamon
1/4 teaspoon ground nutmeg
2 tablespoons packed brown sugar
1 teaspoon grated lemon zest
1/2 cup butter, softened
2 tablespoons milk

Scrub and pierce the sweet potato, then microwave on high for 10 minutes. Allow to cool a little before handling, then peel and puree in a food processor or blender. Measure out 1 cup and blend with brown sugar, lemon zest, butter, and milk.

In a seperate bowl, combine flour, baking powder, salt, cinnamon, and nutmeg. Wisk to combine completely. Stir in the sweet potato mixture until it forms a ball. Roll out and cut into biscuits. Bake at 425 for 10 minutes.
