Can I bake the scone dough at a different temperature than the directions state?

Yes, the dough can be baked at different temperatures to accommodate whatever else you have in the oven. Bake as follows or until lightly browned: 350 degrees F for 10 to 14 minutes; 375 degrees F for 9 to 13 minutes; 425 degrees F for 7 to 11 minutes.
