Clay pot cooking is an old method that can be traced back to the time of the Romans. Romertopf clay bakers come in various sizes, and are unglazed. To use, simply soak the pot in water, add your ingredients, and place in the oven for 45 minutes. The clay absorbs the water, which turns into steam and cooks the food.
Just about any ingredient - meat, vegetable, poultry, seafood, fruit - can be added to the clay baker. You can roast a chicken, roast some beets, or roast garlic - the possibilities are endless. The clay baker can also be used to bake bread.
Since the food is slow-cooked in steam and its juices can't escape, food cooked in a clay baker doesn't require the addition of fats such as oil or butter. Also, food cooked in a clay baker comes out very juicy. Cooking with a clay baker saves a lot of time as well - an entire family meal can be cooked in a clay baker. For example, one could place a whole chicken, some potatoes, some carrots, some broccoli, and some garlic in a clay baker, and have a complete meal in under a hour.
