Mastic – The dried resin of a member of the cherry family, Pistacia lentiscus. It has a light, pine-like aroma and taste. It is usually sold in a form known as “tears,” small nuggets of the dried resin which is always ground to a fine powder before being used. It flavors many breads, cheese pastries, puddings, and preserves and is widely used in the Middle East and is not widely available elsewhere. It is brittle and easily crushed, and takes on the consistency of chewing gum when chewed and so has been popular as a breath freshener for centuries.
