Typically made of a ceramic material, the baker is constructed with a base and a dome-shaped lid. While the base is glazed for ease of clean-up, the remaining surface area of the container is porous to allow the steam and moisture to be held and circulate within the lid to allow the sugar in the roasting garlic to caramelize. The open space in the lid enables more moisture to accumulate thus improving the results when roasting the garlic to be spread on bread or to be used in soups and sauces.
