Depending on where you live, gelatin may be called different things. In the United States and Canada, jelly is often called 'Jell-O'. Jell-O is a brand of gelatin that has become a generic, or typical, name for a lot of gelatin. Like the United States, in Canada "Jell-O" is a normal name for gelatin. In Commonwealth Nations like the United Kingdom and New Zealand, almost all gelatin is called jelly. Also, it is spelled gelatine.
