Simple syrup. A basic sugar-and-water syrup used by bartenders as a sweetener to make cocktails.

Maple syrup is a viscous sweetener derived from maple tree sap. Many people use it in baking in place of sugar or other sweeteners, some use it in tea instead of honey, and it is frequently used as a topping for pancakes, waffles, and other breakfast foods. Since true maple syrup is rather expensive, a wide range of imitation syrups exist.
