Rum is a sugarcane-based liquor first made in the Caribbean in the 17th century. It is made from cane juice or molasses, water and yeast by a process of fermentation. The rum then is aged in wooden barrels and caramel often is added. The majority of the world's rum production still takes place in the Caribbean, but it is also made in countries like U.S., Australia and Canada. Rum is a popular ingredient in many foods, including rum cake, although there are certain brands of rum that work better in rum cake.
