This recipe was created by Oliveto Pastry Chef Jenny Raven for Community Grains and it is a very popular scone in their cafe. They make it with their Hard Red Winter Wheat Flour bringing a wonderfully nutty flavor to the scone while the butter and buttermilk keep the texture light.
Preheat oven to 350 degrees and line a baking sheet with parchment paper.
Measure the dry ingredients into the bowl of an electric mixer. Cut the cold butter into 1? cubes and add it to the bowl. With the paddle attachment, mix until the butter pieces are broken into 1/2-chunks and the mixture is becoming mealy. (If you don-t have a mixer you can use a combination of a pastry cutter and your hands) Do not completely mix the butter in. Stop the mixture and reach into the bowl to see if any large chunks still remain. If so, smear them between your fingers.
Add the currants and mix briefly to distribute.
Add eggs and buttermilk and mix just until the dough comes together, stopping the machine once to scrape the more gooey dough off of the beater and to turn some of the drier dough from the bottom of the bowl up to the top of the mix.
Turn the dough out onto a well-floured surface and roll to an even 3/4-patty. Cut into even triangles or with a 3- circular cookie cutter (the weight should be about 4 1/2 oz) and space evenly onto a parchment-lined sheet pan.
Brush the tops of the scones with egg wash and bake until the tops are golden brown (about 15-20 minutes).
