Just thought I'd share one of my favorite recipes: Buttermilk Blueberry Scones from Average Betty. She has really excellent step by step photos. You don't have to actually purchase buttermilk, just sour milk using 1 TBSP white vinegar or lemon juice per 1 cup of milk. Do this step first because it needs to sit for five minutes. She suggests using frozen blueberries because fresh bleed too much. I think she said this backwards. Fresh blueberries bleed less than frozen. I've been getting really good fresh blueberries at the store lately.
Of course I've made changes to this recipe to suit my tastes, and I think it is improved to perfection! Instead of cutting with the biscuit cutter, I prefer to just dust my baking stone with a little flour, form a disk and cut the traditional scone triangles. You will want to separate them some so that they don't bake together. I do not coat with the buttermilk at the end, but sprinkle sparkling sugar on top and pat them in lightly before popping them into the oven. After baking, I make a glaze out of powdered sugar, milk, and vanilla. Drizzle this glaze over the cooled scones. YUM!
