Clamato, , is a commercial drink made of reconstituted tomato juice concentrate and sugar, which is flavored with spices, dried clam broth and MSG.[1] It is made by Mott's. The name is a portmanteau of clam and tomato. It is consumed in Canada, Mexico, and the United States, to a lesser extent. It is very often mixed with alcohol to make a Caesar, a drink similar to a Bloody Mary.
