Being steel and not cast iron, the Cherished Czech cookware functions the same from stovetop to oven, but is so much lighter. The Tse & Tse Cherished Czech Cookware is enameled cookware that is based on a casserole the design duo brought back from Prague a very long time ago. It has been so useful and nothing is capable of destroying it, they say. They loved the principle of it so much that they designed their own interpretation in a series of black steel cookware with a heavy bottom and blue enameled interior. What a great and unique presentation these casseroles make when they are put in the middle of the table and comfort food is served family style.
