The round shape of the classic HIC Porcelain 4 oz. Ramekin / Souffle Dish (size 2) uniformly distributes heat. One of the tricks to making a perfect souffle is using a round, straight-sided dish with an outset lip at the rim. 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 souffle to continue to rise above the rim without sticking and rising off-kilter. In addition to souffle, the dish can also be used as an individual gratin, casserole or as a baked custard dish for panna cotta, creme brulee and flan. The dish is also the perfect size for salt, fresh minced herbs and other mise-en-place (individual prepped items) you need within easy reach of the stove. HIC Porcelain is oven, broiler, microwave, freezer and dishwasher safe. Diameter: 3", Capacity: 4 oz. Made by HIC.
