teaspoon baking powder
cup (1½ sticks) unsalted butter
cup currants (optional)
Tablespoon heavy cream, for brushing
Preheat oven to 400 degrees F. Combine the flour, sugar, salt, baking powder, and baking soda in a large bowl. Ad butter and mix with your fingers to a coarse meal. Add buttermilk until just combined. Add currants, if desired (cooking raisins, cherries or cranberries can also be used). Transfer dough to a floured board and divide into 2 parts. Roll each to 3/4" thick rounds. Cut each round into 8 wedges and place slightly separated on a greased baking sheet. Brush tops with the cream and bake for 15 minutes or until lightly brown. Serve warm, split in half with butter and marmalade.
