Mill the wheat berries on the finest setting of your grain mill using a large mixing bowl. Let the flour cool by either placing the bowl uncovered in the freezer for 15 minutes or covered for 30 minutes at room temperature.

Place the ball of dough onto a small parchment lined baking sheet and press into a disc. Put the baking sheet into the freezer and set a timer for 30 minutes.
Take the dough out of the freezer and lift it, still on the parchment paper, onto your counter. Add clean parchment paper to your baking sheet. Cut the dough into 8 wedges. Lift each wedge and place onto the parchment lined baking sheet. At this point you can either bake them or place them back in the freezer to freeze completely and transfer to a freezer bag until ready to bake.
To bake the scones, preheat your oven to 400℉. Bake the scones for 25 - 30 minutes until light golden brown and no longer doughy in the middle. Serve warm.
