Make-Ahead Tip: To make ahead, follow the instructions above through brushing the tops of the shaped scones with butter and sugar. Place the scones on a baking tray, then transfer the entire tray straight to the freezer for 30-45 minutes. (This will flash freeze the scones so they are easier to work with and keep their shape.) Remove the tray, and wrap each scone in a small piece of plastic wrap. Place wrapped scones in a zip-top freezer bag, seal, and store in the freezer for up to 3-4 months. When ready to bake, unwrap frozen scones, place directly on a baking tray, and bake at 375 F/190 C for 20-25 minutes, until the tops are lightly browned.
