This solid aluminum baking sheet is proudly made in America and is 13 x 18 with one inch rolled sides. Aluminum is the best heat conductor and will make very even cookies or roast your vegetables perfectly.
Cookie sheets, jelly rolls & baking sheets are all in essence the same thing. Jellyroll pans traditionally have shallow sides, usually 3/4 of an inch to an inch, and cookie sheets can have these same sides or be completely flat with no edges in order to slide the cookies right off.
