Native to the Mediterranean, olives are the small, oily fruits of the Olea Europaea tree. These fruits are actually too bitter to be eaten off the tree, so they must go through processing after picking.
First the olives are separated by color and size and dunked in lye. Then they're cured dry with salt, brine, oil or dry-roasting. Finally, they're packed in oil or vinegar. This process varies by region and the main olive-producing countries of Spain, Italy, Greece and France all have their own specialties to offer.
There are hundreds of different olive varieties and the flavor of each depends on when the olives were picked and how they were processed and packed. Green olives are picked when not yet ripe, purple olives when just ripe, and black olives when they're overripe. Here are some popular varieties you might like to try:
