Sweet Potato Biscuits:
- 1 pound sweet potatoes (2 to 3 potatoes)
- 2 tablespoons buttermilk
- 1/4 teaspoon freshly grated nutmeg
- 2 1/2 cups all-purpose flour, plus extra for dusting
- 3 tablespoons brown sugar
- 1 1/2 teaspoons baking soda
- 3/4 teaspoon salt
- 1 1/2 sticks cold butter, small diced
- 1 tablespoon vegetable oil
- 2 tablespoons butter, melted and slightly cooled
- 14 slices honey baked ham (or your favorite ham), torn into pieces to fit the biscuits
- Blackberry Balsamic Drizzle, recipe follows
- Arugula, for serving
- Special equipment: 2 1/4-inch round biscuit cutter.
For the biscuits: Preheat the oven to 425 degrees F. Poke the sweet potatoes with the tines of a fork and bake until tender, about 1 hour. Let the potatoes cool, and then peel them, discarding the skins.
Whisk together the flour, sugar, baking soda and salt. With your fingertips or a dough cutter, cut in the cold butter until pea-size chunks are formed. Fold in the sweet potato puree until just combined, being careful not to overwork.
Dust a work surface with some flour and turn the biscuit dough onto the counter. Form the dough into a 3/4-inch-thick disc. Using a 2 1/4-inch round biscuit cutter, cut out 14 biscuits, starting on the outside of the disk and working your way in. You may need to reshape the last bits of dough back into a disk to get all 14 rounds.
Grease a 10-inch cast-iron skillet with the vegetable oil and place the biscuits in the skillet, working from the center out. The biscuits should be a tight fit and nestled against each other. Brush the biscuit tops with the melted butter and bake until golden, 15 to 18 minutes.
For the sandwich build: Split the hot biscuits, place some of the torn ham on the bottom half, drizzle the Blackberry Balsamic Drizzle over the ham and then pile some arugula on top for a peppery bite.
