About Olives
Cultivated for over 6,000 years, olive trees find their origins in the Mediterranean, which still contributes to over 90% of the world's olive production. Thriving exclusively in hot, dry climates with mild winters, these trees take 12 to 15 years to bear full crops and can live up to an impressive 600 years.
Specialty markets offer table olives from various regions, including Greece, Spain, Italy, France, Israel, Morocco, and newer entries from Californian olive groves.
Despite their fruit-like appearance, olives are botanically classified as drupes, akin to cherries and peaches, featuring fleshy pulp, a single seed or pit, and an inner stone containing the seed.
Olive Ripeness
Ripening from green to black, olives progress through stages of reddish, brown, and purple hues. Green and black olives may not necessarily be distinct varieties, as they are harvested and cured for the table at various ripeness stages.
Straight from the tree, olives are inedible due to the bitter compound oleuropein; thus, they require curing before consumption.
The flavor of olives, influenced by factors like ripeness, climate, and handling, primarily hinges on the curing method. Brining or dry-curing are the two predominant methods, each contributing distinct characteristics to the finished product.
Olive flavors span a broad spectrum, appearing in various colors and sizes, reflecting the variety and harvest-cure timeline. They may range from strong to mild, salty to vegetal, buttery to nutty, and spicy to slightly bitter.
Buying Olives
When purchasing olives, look for unbruised, clean, and firm ones. Brine-cured olives should be plump with smooth, shiny skins, while dry-cured olives should appear meaty and not overly dry.
To preserve olives, store them in the refrigerator, keeping them moist either in brine or sprinkled with olive oil. Allow them to reach room temperature before serving, and if brine-packed, drain and rinse before consumption.
Cooking with Olives
When cooking with olives, reduce the recipe's salt content, as olives contribute their own salty flavors. Olives contain 5 to 20 calories each, with a high proportion of healthy mono- and polyunsaturated fats.
