1 pound (about 4) sweet potatoes
2 ½ cups all-purpose flour
4 teaspoons baking powder
2 Tablespoons sugar
1 teaspoon salt
¼ teaspoon cayenne pepper
8 Tablespoons (1 stick) unsalted butter
( I used half soy margarine)
¼ cup milk
1/ Heat oven to 400. wash the sweet potatoes and prick all over with a fork.
Place on a baking sheet; bake until soft, about 1 hour. When cool enough to handle, scoop out flesh and press through a sieve (you should have 1 ¼ cups puree) Set aside.
2. In a mixing bowl, combine the dry ingredients. Cut in butter until mixture resembles coarse meal.
3.In another bowl, whisk together milk and sweet-potato puree. Add to dry ingredients and mix until well combined.
4. Place dough on lightly floured board, knead once ore twice, and pat out to ½ inch thick. I just sliced them into square shapes. Bake on cookie sheet (with parchment paper if possible) for about 20 minutes until golden brown.
