Looking nothing like traditional bakeware but borrowing many of its best characteristics, Lekue's heart-shaped cake pan cooks evenly, releases food easily, and is made of FDA approved food grade silicone. It takes some getting used to, but the pliable silicone construction carries many advantages such as immediate cool-down, the prevention of burnt edges and crusts, and a foldability that extends storage options. Cooking times may be slightly shorter and the versatile pan comfortably handles everything from sweet cakes to savory casseroles or gratins. Nonstick surfaces help food to release easily but greasing is still recommended--especially if regularly being washed in the dishwasher. Freezer-, microwave-, and oven-safe up to 500 degrees F, the pan seamlessly transitions from cold to hot and back again if needed. Contact with direct heat sources such as burners or hotplates should be avoided and sharp metal tools can damage or cut the material. The pan measures 9 by 9-3/4 by 1-3/4 inches and benefits from a quick rinse before use as small crumbs and particles easily adhere to its rubbery surface.
