Large Rosette Cookie Mold. Rosettes are a dessert that originated in Sweden and Norway and have found popularity worldwide. They are cookie-like pastries that are deep fried and commonly have the edges dipped in frosting or sugar. To make a batch of your own, attach this rosette iron to a handle (sold separately item 7166) and heat in hot oil. The mold must be seasoned before use to ensure the easiest release. Dip the hot rosette iron into the batter and put back in the hot oil until a crisp shell is created. Voila!
