1oz Package. Do not confuse the flavor of licorice with that of anise oil, which is not related to licorice at all and is a poor imitation. Licorice has been used for everything from, cough remedies to ulcer cures. The root imparts a very characteristic flavor and is surprisingly sweet. It contains glycyrrhizin, a substance 50 times sweeter than sugar, and is often added to chocolate to enhance sweetness.
