Romertopf is the brand name for a manufacturer that specializes in making clay pots for baking and roasting foods in the oven. The pottery is unglazed and requires presoaking when it is being used. It also acquires seasoning, which will set certain flavors into the pot and will change the way the Romertopf looks because it will darken and add spots and coloration to the pottery. This allows for seasoning transfer from one meal to the next. Pots like these have been used for hundreds of years for cooking. They are durable and decorative to serve from. Cleaning Romertopf is easy, but different from other types of pots.
Allow the Romertopf clay pot to cool naturally. Do not immerse it in cold water or place it in the refrigerator when it is hot. Clay pottery is sensitive to temperature changes.
Remove all remaining food to other storage containers.
Place the room temperature Romertopf clay pot in the sink and fill the pot with water. Never use soap or the soap flavor will transfer into your next clay pot meal.
Use a Kliner pad to scrub the walls and bottoms of the pot to loosen any stuck food. The Kliner pad is recommended and sold by Romertopf. A natural loofah also can be used. A loofah is a fibrous part of the fruit of a plant from the Luffa genus. The loofah is traditionally used for scrubbing pots but it isn't abrasive and doesn't scratch like steel wool or leave metal bits in the porous surface of the clay.
Increase the water temperature in the pot by running hot water and letting it overflow into the sink until the water is too hot to touch with the hand. Use a loofah with a handle, allowing the heat of the water to help in removing extra stubborn food stains.
Use baking soda and water and scrub the pottery lightly if the pottery develops a bad odor.
Rinse the pottery with distilled water to prevent the buildup of minerals on the natural clay surface. Air dry the pottery until it is completely dry. Invert the lid and place a paper bag between the pot and the lid to prevent chipping.
Allow the Romertopf to season (some discoloration and staining is actually seasoning). This means that pots will take on flavors and return those flavors to the next meal. Keep separate pots for differently spiced or flavored meals. Don't try to remove the seasoning.
Immerse your cooking clay pots in water for 15 to 20 minutes before each use and always put the room temperature pot into a cold oven allowing the pot and oven to heat at the same time.
Store the pottery dry and clean it regularly when not in use to prevent micro-organism growths.
The pottery can be washed in the dishwasher without soap.
Soaps used on clay pottery will enter the food and make it taste bad. Don't use soaps.
