Olives are small, oval-shaped fruits that grow on olive trees, primarily found in the Mediterranean region. They come in various colors, including green, black, and purple, depending on their ripeness. Olives are rich in healthy fats, particularly monounsaturated fats, and are often used to produce olive oil, a staple in cooking and salad dressings. In addition to being consumed whole, olives are commonly found in Mediterranean cuisine and can be served as snacks or appetizers. They are often cured or brined to enhance their flavor and reduce bitterness. Olives are also a key ingredient in dishes like tapenade and pizza.
