What are Olives?

Is Eating Too Many Olives Bad for You

Olives are small, oval fruits produced by the olive tree (Olea europaea). Belonging to a group of fruits known as drupes, or stone fruits, they are related to mangoes, cherries, peaches, almonds, and dates. The olive tree is an ancient plant, native to the Mediterranean region, and has been cultivated for thousands of years.

Fossil evidence suggests that the olive tree existed as far back as 20-40 million years ago. 

The domestication of the olive tree is believed to have started approximately 6000 years ago in the Mediterranean region – an area spanning modern-day Israel, Palestine, Syria, Turkey, and Lebanon. This region is still one of the largest producers of olives today, along with Spain, Italy, and Greece.

Processing and Market Forms

Olives are typically harvested in the green to purple stage. Raw olives are naturally very bitter due to a compound called oleuropein and must be cured before they are edible.

The curing process can be done in several ways – through lye curing, water curing, brine curing, or dry curing – each of which affects the flavor, texture, and color of the final product. After curing, olives are often fermented to enhance their flavor.

In the market, you will commonly find olives in several forms:

  • Whole olives, both green and black, which can be pitted or unpitted.
  • Sliced or chopped olives, often used as pizza toppings or in salads.
  • Stuffed olives, where the pit is replaced with items like pimientos, garlic, or almonds.
  • Olive paste or tapenade, used as a spread or in cooking.
  • Olive oil, which comes in varieties like extra virgin, virgin, and light.

Culinary Uses

Olives are a versatile ingredient in the kitchen. They can be used in a wide range of dishes, providing a salty, tangy, or even slightly sweet flavor depending on their variety and preparation.

  • In salads, olives add a burst of flavor. Greek salad, for instance, is known for its Kalamata olives.
  • In pasta dishes and sauces, olives provide a depth of flavor. Puttanesca sauce is a classic Italian sauce with olives.
  • On pizzas and flatbreads, olives are a popular topping.
  • In stews and braises, olives can provide a contrasting flavor profile.
  • In baking, finely chopped olives can be added to bread for extra flavor.
  • As a snack, olives are often served on their own or as part of a mezze platter or antipasto.

Overall, olives are a valuable addition to many dishes, not only for their unique flavor but also for their nutritional benefits. However, due to their high sodium content, it’s advisable to consume them in moderation.
