mastic

"Mastic" has an interesting double life. First, it is the aromatic resin taken from the mastic tree, a slow-dripping sap that people have chewed like gum since ancient times. It is still used in some traditional sweets, baked goods, and liqueurs. But you may also see "mastic" in a hardware store. There, it means a thick adhesive or sealant used in building and repair work. Whether it is in a Greek dessert or around a window frame, the word usually points to something sticky and useful.

Imagine strolling through sun-drenched groves on the Greek island of Chios. There, growers collect a special resin from the mastic tree, a form of Pistacia lentiscus. This pale, translucent substance hardens into tear-shaped drops that people have chewed like gum for centuries. Writers from the ancient Greek world mentioned it, and it became known not only for chewing but also for its pleasant smell and taste.

But mastic isn't just for chewing. Its fresh, pine-like flavor makes it a valued ingredient in Mediterranean cooking. It appears in sweets, breads, ice cream, and liqueurs, especially in Greek and nearby food traditions. It has also been used in traditional medicine, especially in connection with digestion and oral health.

In the modern world, the word has also taken on an industrial meaning. In construction, "mastic" often means a thick paste used as an adhesive, filler, or sealant for joints, tiles, glass, or metal. The word comes from the Greek mastikhe, linked to chewing and related to the English verb masticate. So even if you never taste the tree resin itself, the word still carries the same old idea: something chewy, sticky, or able to bind things together.
