1 1/2 cups all-purpose flour, preferably organic, such as Heartland Mills
1/4 cup sugar
1 tablespoon baking powder
1/2 tablespoon baking soda
1/2 tablespoon salt
1/4 pound unsalted butter
1 1/4 cups rolled oats, preferably organic
1/2 cup buttermilk, plus a few more tablespoons for brushing on top
Sugar, for sprinkling (regular sugar, or turbinado sugar, also called sugar in the raw or coarse sugar)
Heat oven to 350 degrees F.
Pour the orange juice over the raisins and set aside.
In a medium-size bowl, sift together flour, sugar, baking powder,
baking soda and salt. Work the cold butter into the dry ingredients
with fingertips or a pastry cutter until the mixture resembles coarse
cornmeal. (A few larger pieces of butter are fine — they add
to the flakiness.) Add the raisin/orange juice mixture and the oats.
Stir with a fork to combine.
Add the buttermilk and stir just until the dough gathers in a ball.
(If the dough appears a little dry, add a teaspoon or so more buttermilk.)
Do not overwork the dough!
Turn the dough out onto a lightly floured surface. Shape the dough
into a round about 1 inch tall and 8 inches across. Cut the round
into 8 wedges. Place on a parchment-lined or ungreased baking sheet.
Brush lightly with buttermilk and top with sugar.
Bake in preheated oven for 25 to 30 minutes, just until the top is lightly golden.
