I've been aware of sweet potato biscuits for years, but the opportunity to make them never arose until now. I suspected they might be valued more for the novelty than the taste. I was totally wrong. They are really tasty, and somehow less fussy than my other favorite biscuits. I adapted a recipe from the eminently reliable Dorie Greenspan, so that may have had something to do with it. I used some whole wheat flour and reduced the sugar a bit, to add some substance and cut the sweetness. They are now a permanent part of my biscuit rotation.

Sweet Potato Biscuits
Adapted from Baking by Dorie Greenspan
Dorie's recipe calls for 2 (15-oz) cans of sweet potatoes in light syrup, drained and mashed. I cook sweet potatoes often and tend to hand leftovers, so that is what I used here. Mine were seasoned rather elaborately with ginger, cloves, cinnamon, cayenne vanilla, salt and pepper plus a bit of coconut milk and chopped pecans...whew. But just salt and pepper would be fine.
Makes 9 to 12
1 cup whole wheat pastry flour
1 cup all-purpose flour
1 teaspoon coarse salt
Pinch of ground cinnamon
1 Tbs. (packed) brown sugar
6 Tbs. unsalted butter, cut into cubes and chilled
1 cup seasoned, mashed sweet potatoes
1 egg, for egg wash (optional)
Preheat oven to 425 degrees and line a baking sheet with parchment paper. Whisk the flours, salt, cinnamon and brown sugar together in a large bowl. Add the butter and toss to coat it with flour. Using your fingertips or a pastry blender, pinch and toss the butter and flour until you have a rough, sandy mixture with some pea-size lumps of butter, some ragged flakes and a variety of odd-shaped bits. Do not over work the butter.
Add the sweet potatoes and toss gently with a fork until all the flour is moistened and you have a soft dough. Knead dough inside the bowl 3 or 4 times so that you have a fairly uniform consistency. Turn dough out onto a lightly floured work surface and sprinkle lightly with more flour. Flatten dough with your hand and roll it out into a 1/2-inch thick disk. Flour a 2 to 2-1/4 inch biscuit cutter and stamp out as many biscuits as you can, pushing firmly into the dough and flouring the biscuit cutter each time. Transfer biscuits to prepared baking sheet. Quickly re-roll the dough scraps and make more biscuits until you've used it all up.
If using egg wash, crack egg into a small bowl, add 1 Tbs. water and beat. Using a pastry brush, lightly coat tops of biscuits with egg wash. Bake 15 to 20 minutes, or until puffed and golden brown on the bottom. Transfer to a rack to cool. If you can wait, cool 15 to 20 minutes before serving. Dorie says the sweet potato flavor grows more pronounced, and I agree! Serve with butter.
