Cooking meat in an oven in a closed pan with a small quantity of water constitutes braizing. This cooking process might be called a combination of stewing and baking, but when it is properly carried out, the meat is placed on a rack so as to be raised above the water, in which may be placed sliced vegetables. In this process the meat actually cooks in the flavored steam that surrounds it in the hot pan. The so-called double roasting pans are in fact braizing pans when they are properly used. A pot roast is the result of a modification of the braizing method.
