A versatile dish, these stackable ramekins are perfect for individual desserts, serving sauces at the table, or separating ingredients during food preparation in the kitchen. Le Creuset stoneware offers the ultimate in versatility and is fabulously durable. It can bake in an oven up to 500 degrees F, go in the microwave or under the broiler. It can also go from the freezer into a cold oven so stoneware, food, and oven heat up together. The virtually non-porous stoneware is fired at 2156 degrees F, giving it unmatched strength and durability, making it resistant to chipping, cracking and staining.
