Oven and microwave safe Dishwasher Safe Great for souffl, custards, as a serving dish, etc. Made from glazed fine white porcelain The round shape of the classic HIC Porcelain Souffl Dish uniformly distributes heat. One of the tricks to making a perfect souffl 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 souffl to continue to rise above the rim without sticking and rising off-kilter. In addition to souffl, the dish can also be used as an individual gratin dish or casserole. 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.
