Olive

Olives, from the olive tree, offer salty, savory flavors whole or as oil.
Olives are the small, oily fruit of the Mediterranean olive tree, eaten cured or pressed into oil. On the tongue they are salty and savoury with gentle bitterness, an earthy fruitiness and sometimes a smoky or winey edge, depending on the variety and cure.
Cooks love olives as instant flavour boosters. A handful seasons a pasta sauce, a tray of roast chicken or a simple tomato salad, and blitzed with capers and anchovy they become tapenade. They bring salt, fat and depth in one bite.
Flavor profile
Aroma: fruity, savory
Good to know
Origin: Mediterranean
Forms: whole, oil, paste
Season: Fresh olives are harvested in autumn and winter, but cured olives are a pantry item available year-round.
Nutrition: Olives contain mostly monounsaturated fat and are high in salt from curing, so a few go a long way.
Storage: Unopened jars and cans keep in the pantry for a year or more. Once opened, refrigerate olives covered in their brine or oil, where they last 2–3 weeks or longer. If the brine gets cloudy and slimy, or the olives smell rancid or mouldy, throw them out. You can top up brine with a little salted water to keep them submerged. Olives can be frozen, but they soften, so use thawed ones in cooking.

Salads and Tapenades
Add olives to salads or blend into tapenade for a complex salty-savory depth.
The science of olive
- Fresh olives are inedibly bitter because of a compound called oleuropein. Curing in brine, lye or dry salt breaks it down or leaches it out over weeks to months.
- Green and black olives are often the same fruit at different ripeness. Green ones are picked unripe and taste firmer and sharper; naturally black ones ripen on the tree and taste softer and fruitier.
- Some canned black olives are darkened by exposing green olives to air in an alkaline solution, which oxidises their phenolic compounds. They taste much milder than naturally ripened ones.
- Olive flesh is rich in oleic acid, a monounsaturated fat. That fat carries aromatic compounds from garlic, herbs and citrus, which is why marinated olives soak up flavour so well.
How to choose olive
Choose olives sold in brine or oil, with plump, unwrinkled flesh unless they are a dry-cured style. Unpitted olives usually have better texture and flavour than pitted ones. At an olive bar, look for clean brine and avoid any with a sour, off smell.
