Cane sugar is sucrose which has been extracted from sugarcane, a tropical plant which produces naturally high concentrations of this sweet substance. Humans have been utilizing cane sugar in cooking for hundreds of years, and cane sugar was at one point a major element in global trade. Today, most markets carry cane sugar in a variety of forms, from minimally processed raw sugar to sugar cubes; cane sugar typically tends to be a more expensive form of sucrose, but many people prefer it because they believe it has a superior flavor.
