To Buy:
Buy mastic tears in a specialty spice store or a Greek delicatessen. They are usually sold in packs of just a couple of grams, which is a single serving for making, say, a batch of ice cream.
To Store:
Stored in an airtight container away from heat and light mastic should last for 2 years.
Tips & Tricks:
Mastic added to icecream, custard or sweets gives a velvet texture while not adding much flavour. It can be chewed like gum, and the name mastic was the origin of the verb masticate, to chew.
