Chios mastiha, or mastic, has a distinct, piney taste that people either love or hate. When it dries off the tree, you'll find it in opalescent white pieces of varying shapes and sizes. While perfectly edible in this form—a chewy, slow-dissolving candy—it is also consumed in a variety of other ways. One of the most common, especially in Greece, is known as a submarine. A mastic solution, a ghostly translucent white, is wrapped around a popsicle stick in a sticky blob, then placed in a cup of ice-cold water. The blob is removed, leaving behind a flavored drink. Mastic is also blended into ice creams, cookie doughs, and cake batters, and it is used to flavor everything from salts and sugars to gums, liqueurs, and olive oil. Mastic is said to help with digestive woes and cavities, and depending on how passionate a producer you ask, it can heal pretty much anything.
