Cultivated for thousands of years-its image decorates the walls of Ancient Egyptian tombs-the olive has been inestimably important to the development of cuisine and even civilization. Originally from the Mediterranean, which is still the world’s major producer, olives are now grown in California, Arizona, New Mexico, and much of the rest of the world.

There are dozens of varieties; multiply that by the number of different curing processes (a half dozen or so), and you’ve got yourself a vast assortment to choose from. What we see in the United States is just a small fraction of what’s available in all the different countries and regions that produce and cure olives. Go to any Mediterranean market (that’s Greek, Italian, Spanish, North African, or Middle Eastern, to name just a few) for a far more comprehensive and regional selection.
Olives are green when immature and darken, eventually turning black, as they ripen. Most olives are picked green for curing; those intended for olive oil are allowed to ripen further; and some are picked quite dark.
As anyone who’s ever eaten an olive straight from the tree knows, curing olives is essential to making them edible; they contain an extremely bitter-tasting chemical called oleuropin, which is minimized or eliminated by curing.
Olives are most often cured in oil, saltwater, lye, or salt; the method will determine the fruit’s ultimate flavor, texture, and final color. Often herbs or spices are added to further enhance flavor. Following are brief descriptions of the most common olives:
Black or Mission: Most often pitted and canned and nearly tasteless; picked when unripe or green; cured in lye and then oxygenated, which turns them black.

Kalamata:Widely available, salty, and sometimes mushy, though not unpleasantly so; dark brown, purple, or black. Picked when ripe or almost ripe, then cured in saltwater or red wine vinegar. Decent standby.
Manzanilla or Spanish: Big, green, rather crisp, and often stuffed with pimientos or garlic cloves. Usually picked young; cured in lye, then brined for 6 months to a year. Can be delicious.
Niçoise: From Nice, France; dark red or brown, small but plump, with a slightly sour flavor. Picked ripe, then cured in saltwater. Flavorful, but a lot of pit for a small bite.
Moroccan: Also called oil- or dry-cured; shriveled, shiny, and jet black. Picked ripe, then cured in oil or salt, sometimes with herbs. Excellent staple, as they keep forever and can be plumped up by marinating in oil.
Picholine: From France; green, almond shaped, and crisp. Picked green, then cured in saltwater or lime and wood ashes, then brined, sometimes with citric acid, giving them a tart flavor. Delicious.
Buying and storing: There’s no guesswork in canned or jarred olives. Loose olives should be firm and not dried out (unless oil- or dry-cured, in which case they are shriveled and not stored in any liquid). Taste one before buying.
Keep in mind when paying by the pound that any liquid you include is adding weight (olives in a liquid will keep longer, however). Generally, don’t buy more than you’ll use in a week or two, though they’ll keep longer (dry-cured olives, which are sold without liquid, keep well for weeks). Refrigerate.

Preparing: Remove the pit by slicing the flesh lengthwise and digging it out with your fingers; or crush with the side of a knife and pick out the pit; or use a pitter. If you like, you can reduce the saltiness by rinsing or soaking in water for 20 minutes or so or boiling for 30 seconds beforehand.
Other vegetables to substitute: Caper berries or capers.
