Product Description:
Emile Henry Red Round Covered Casserole: An innovation in ceramics technology, Emile Henry's 2.6-qt. Flame Top Casserole works directly on a gas flame or an electric or halogen hob without a diffuser and without fear of cracking or breaking. Extremely durable and versatile, it can also be used in the broiler or oven and transported directly to the table, refrigerator, or freezer. Much lighter than many comparable metal cookware products and 30% lighter than Cast Iron, it cleans up easily and is both microwave and dishwasher-safe. Plus, cooking in ceramic is still the best way to preserve the flavors and nuritional qualities in food, as well as develop the aromas. The convenient lid features small bumps on its underside that favor the condensation process and return important vapors back into the food.

Rating : - Simply the best!
I've used a lot of different types of cookware through the years---cast iron, clad cast iron, aluminum clad, teflon coated, etc (both lower and higher priced). The FLAME TOP series are the only ones that can go in the oven, on the stove top, in the fridge, microwave, etc. Fantastic heat distribution with no hot spots or burning. Extremely easy to keep clean. Due to higher cost, I've accumulated a set over the recent past and have donated all of my other cookware! Buy one and try it, you WILL be amazed!
