The HIC Porcelain Heart-Shaped Ramekin / Soufflé Dish uniformly distributes heat. The straight sides of the dish push expanding egg whites in the desired, upward direction. The outset lip at the rim reduces contact of batter to the dish, allowing your soufflé to continue to rise above the rim without sticking and rising off-kilter. In addition to soufflé, the dish can be used as an individual casserole or gratin dish, or for baked custard dishes like panna cotta, crème brulee and flan. HIC Porcelain is oven, broiler, microwave, freezer and dishwasher safe. Dimensions: 3-3/4-Inch, Capacity: 6-Ounce
