what size pan to use when recipe calls for jelly roll pan
Its design allows air to circulate freely around the cookies so they bake and brown evenly. A jelly-roll pan (either 15 Â½ by 10 Â½ inches or 18 by 12 a.k.a. a half-sheet pan) has 1-inch-high sides and is perfect for making cake rolls; it can stand in for a cookie sheet in a pinch. It's also a terrific roasting pan for veggies and more.
