Combine the dry ingredients and grated nutmeg in a medium sized bowl.
Cut in the butter and crumble quickly with your fingers until it forms a rough granular texture.
Add the berries and chips and toss to mix.
Add about two thirds of the buttermilk and begin to form a dough. Add the rest slowly until a ball has JUST formed. (It may be a bit lumpy and unwieldly due to the berries. Get it to the point where it all sticks together without overworking the dough.
Form into a flattened circle about the circumference of a dessert plate.
Cut in half, form each half into another circle.
Cut each circle into quarters.
Place on a silpad on a baking sheet and bake for 18-22 minutes at 425°F until they are browned and when tapped sound a bit hollow.
Remove from oven and let cool for a couple minutes before serving with some Devonshire Cream that has been blended into some whip cream.
Notes
* If you don't have buttermilk, put 1 tablespoon white vinegar into 1 cup white milk and set aside ** If you would like a berry scone, add just before you add in the milk. If you want to use raspberries, I would use frozen so they don't get mushed.
