From Dutch ovens to souffle dishes, here's how to spring for the right pan.
Jelly Roll Pan
A jelly roll pan is a 15 x 10 x 1-inch pan that's used to make thin cakes, such as sponge cakes and jelly rolls. Some people call them baking or cookie sheets, but technically, a baking sheet has a rim on just one or two sides. Jelly roll pans come in shiny and dark finishes, and may have nonstick surfaces.
