Read the passage from Sugar Changed the World.I wanted to know more about the beguiling Nina, and my cousin had plenty of stories to share. He told me that her grandfather was a Russian serf—a farmer who could be bought and sold by the noble who owned his land. Family legend has it that this serf, a remarkable and intelligent man, helped to change the course of the history of sugar. In the early 1800s, the British controlled most of the sugar plantations of the Caribbean and the sea routes to Europe. As a result, their rivals were desperate to find a new way to create sugar. They turned to beets.
