Mastic

Mastic (mastaki) is the resin of a Mediterranean evergreen tree related to the pistachio tree (Pistacia lentiscus). Mastic resin is extracted by slashing the trunk and large branches of the tree. As the resin seeps out it hardens into small translucent lumps. It is widely used in making chewing gum, incense, varnish, and for flavoring liquors, pastries, and desserts. In medieval times, it was used in meat dishes and stews, as well. Since mastic tends to melt rather than dissolve into the food, it is advisable to pulverize the translucent light-yellow lumps before adding them. It also comes in the form of cream, much like marshmallow cream. This variety is good only for desserts because it is sweet.
