Römertopf chicken is so easy to do and it is wonderful! Crispy skin. Moist. From Wikipedia, we see that,
Different cultures have different techniques of cooking food in pottery. Some design pots that are fully finished by burnishing and therefore don’t require the pot to be soaked each time before use. Some are unfinished and work well when soaked for about 30–45 minutes in water, each time before use. The design and shape of the pot have been slightly modified from one culture to another to suit their style of cooking. Seasoning is an essential part of cooking in clay. Seasoning is done by making a broth with flour (rice or wheat) and vegetable cooking oil. These ingredients are mixed to the water in the pot and brought to a boil…The food inside the pot loses little to no moisture because it is surrounded by steam, creating a tender, flavorful dish. The evaporation of the water prevents burning so long as the pot is not allowed to heat until it is completely dry. Because no oil needs to be added with this cooking technique, food cooked in clay many times is lower in fat compared with food prepared by other utensils. Pots also seal all the nutrients inside the pot by locking steam in. The unglazed pottery utensil made from clay is inert or non-reactive and does not leach into food. Earthenware cooking pots are made from special clay that can withstand heat in an oven or on the stovetop.
Here are some photos of the Chicken Römertopf that we made. And as a note, using a Römertopf is very similar to using a tagine in Moroccan cooking. Both techniques, and several other clay pot techniques, use steam to maintain the moisture. Enjoy!
