In a large bowl whisk together the dry ingredients.

Add liquid ingredients and egg to flour mixture. Using a hand blender mix in wet until just incorporated. Now cut in the very cold butter.

Mix until incorporated. Add in frozen blueberries. Turn dough out onto a lightly floured surface. Gently knead into a soft ball. Dough will be a bit sticky. Add a bit of flour to work surface if it too sticky to work with.

Now I return my dough back into the bowl and refrigerate. This is when I preheat my oven to 400 degrees. Once oven comes up to temperature I take dough and place it on a parchment paper lined baking sheet.

I pat dough into a round circle of about 8 "diameter. Keep dough about 1/2" thick. Score the tip of dough lightly into 6 cross cuts. Brush with extra heavy cream and you may sprinkle top with some coarse sugar. I use sugar in the raw.
