Our Superstone® Baking Stone duplicates the effects of a professional pizzeria oven. The stone absorbs moisture, creating a crispy pizza crust! The round shape is great for a traditional-style pizza. Also try breads, pretzels, cookies, and anything else that uses dough on your Superstone®. We're sure you'll think it's "super!". To clean, simply scrub under hot water -- do not use soap. Superstone® measures 15" diameter. 16" with the rack. Includes recipes.
