A round,
flat griddle on which Tortillas are cooked. In Mexico, comals
are used
over open fires are usually made of unglazed Earthenware.
Those intended
for use with electric and gas heat are more often
made of a light metal,
such as tin. The earthenware and thin metal
allow fast heat penetration,
thereby cooking the tortillas quickly -
important so they don't become
dry and brittle.
