I always thought that scones were a little heavier than biscuits, but these are light and fluffy, thanks in part to the FOUR teaspoons of baking powder, and the two eggs. These surprised me when they puffed up so high, and maybe next time I'll flatten the dough out just a little more. I made two rounds about 8" in diameter, then cut one into 6 wedges and the other into 4, just for comparison.
I used a mix of (mostly) sharp Cheddar and Parmesan, but of course you can experiment and mix it up any way you'd like!
1 ½ cups sharp cheddar, grated (or a mixture of cheeses)
3 cups all purpose flour
4 teaspoons baking powder
1/2 teaspoon baking soda
1 1/2 teaspoons salt
1 1/4 teaspoon dry mustard powder
1/2 cup unsalted butter
1 cup milk
Preheat oven to 425º F.
Line a baking sheet with parchment paper. Grate cheese(s) and set aside.
In a food processor, whisk together flour, baking soda, baking powder, salt and dry mustard. Pulse in butter to make a crumbly mixture. Add the cheese. Turn the whole mass out into a large bowl. Make a well in the center. Stir in eggs and milk to make a shaggy dough. Knead on a floured board to make a soft but cohesive mass. Shape into two rounds and cut each round into 4 or 6 wedges. Paint them with melted butter and/or dust with flour.
Bake at 425º F. for 5 to 8 minutes. Reduce heat to 400º F. and continue baking until golden and cheesy looking, about 8-10 minutes more.
