French cooks often roast meats and poultry in a deep porcelain dish as opposed to a metal one because porcelain conducts heat gently and evenly and is easy to clean. Our dish is also useful for other foods that require a deep pan-be it a vegetable casserole or a fresh-fruit crisp. The underside is left unglazed for maximum heat absorption. Our roasters are made by Pillivuyt, a renowned French manufacturer that has supplied chefs and home cooks with restaurant-quality porcelain products since 1818. Made of high-fired porcelain. Microwavable; oven and dishwasher safe. Made in France.
