1 cup coarsely chopped or sliced fresh cranberries
1 cup coarsely chopped walnuts
Zest of 1 orange, optional
2 tablespoons granulated sugar
2 1/4 cups all-purpose flour, 10 ounces
2 1/2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
6 tablespoons cold butter, diced or shredded
3/4 cup buttermilk, well shaken
Instructions
Heat the oven to 425 F and line a large baking sheet with parchment paper.
Combine the cranberries, chopped walnuts, orange zest (if using), and granulated sugar in a bowl; toss to blend and set aside.
In a large bowl, combine the flour, baking powder, baking soda, and salt; whisk to blend. Add the diced butter. With your fingertips or a pastry cutter, work the butter into the dry mixture until it resembles coarse crumbs.
Add the cranberry mixture and stir to blend the ingredients.
Add the buttermilk and stir with your hands or a fork until the mixture clumps together. If the mixture is too dry, add more buttermilk or milk in very small amounts. Move the clumped mixture to a lightly floured surface and knead a few times to form a soft dough.
Pat the dough into a circle or square about 1/2-inch thick or slightly thicker.
Cut out biscuits with biscuit cutters or use a knife to cut them into squares or wedges.
Place the cut-out biscuits on the prepared baking sheet and bake until the tops are lightly browned, about 12 to 15 minutes.
