If you want to make these ahead for the freezer, here is what you do. After you cut them out, brush with cream and add the sugar and lavender, put on cookie sheet and freeze. When they are solid, remove from cookie sheet and put in freezer bags or containers.
To bake frozen scones, here's what I do -- turn the oven on, THEN remove scones from freezer and put on a baking sheet. When the oven has preheated, then put your scones in to bake. They will still be partially frozen but believe me, they come out perfect.
