My student asked me this and I really don’t have a clue. The dictionaries both seem to indicate dry heating, often in an oven. So is there a difference between roasting something and baking it?
Roasting is for meats, and baking is for yummies. Same oven, same heat.
They are the same. One roasts a joint, and bakes a pie, but there isn’t any difference between the two methods.
However: roasted beets; baked chicken.
The traditional (Medieval) method of roasting meat involved putting it on a spit over a fire and rotating it as it cooked, catching the drippings and basting it from time to time. Baking involved a container.
