1-1/2 cups rolled oats, not instant
1-1/2 cups all-purpose flour
1/4-cup sugar
1-1/2 tsp. baking powder
pinch of salt
1-1/2 sticks (6 oz.) unsalted butter, cut into half-inch pieces, chilled
1/4-cup finely chopped candied orange rind (1-1/2 oz.)
3/4-cup buttermilk
1 Tbs. heavy cream
1 Tbs. turbinado sugar
softened butter and marmalade for serving
Instructions:
Preheat oven to 375 degrees F and position a rack in the center.
In a medium skillet, toast the rolled oats over moderately high heat, stirring constantly, until golden and fragrant, about 5 minutes. Transfer to a plate to cool.
In a large bowl, combine flour with sugar, baking powder and salt. Add the butter, and using two knives or a pastry blender cut in the butter until the mixture is the size of small peas.
Stir in the oats and orange rind.
Make a well in the center and add the buttermilk.
Mix the dough with your hands and then turn onto a floured surface and pat into an 8-inch round, about a 1/2-inch thick. Pinch together any cracks around the edges.
Brush the top with cream and sprinkle with the turbinado sugar.
Cut the round into eight wedges and transfer them to a large baking sheet.
Bake until golden on top and bottom, about 25 minutes.
Transfer to a wire rack to cool slightly. Serve with butter and marmalade or jam.
