Wade wanted blueberry, and the boys wanted chocolate chip, so I made half and half.
Here's what you'll need:
(I halved this recipe. Dumb choice. 6 scones didn't last long. This recipe makes 12. Make the whole thing.)
Mix the sour cream and baking soda together in a small bowl. Set aside.
In a larger bowl, mix the flour, sugar, baking powder, and cream of tartar. Cut the butter in with a pastry blender (the thingy I am holding in the photo below), or a fork, or two butter knives used scissor fashion. You'll want the mixture to look like fine crumbs.
Then add the sour cream mixture and the egg. Mix until just blended. I didn't mix in my add-ins, I just pressed them into the tops of the scones, but if you want to mix yours in, do it at this point.
