The Romertopf vegetable clay baker is perfect for roasting fresh veggies. Vegetables cooked in a clay pot requires no liquid unless specifically called for. The result: Full flavor and taste and all the essential nutrients and vitamins are retained. The taste is truly superb. You can cook all kinds of food without adding any fat, in line with the demands of modern dietetics. The Romertopf is made of a special porous clay and is unglazed inside and out allowing it to breathe during the cooking process. By soaking the pot in water before cooking, moisture is absorbed by the clay. The tiny water particles are released during cooking, penetrating and blending with the natural food juices, increasing flavor, tenderness and enhancing aroma.
