Definition & Meaning of "bitter orange"

What is a "bitter orange"?

Bitter orange, also known as Seville orange or sour orange, is a citrus fruit with a tart flavor and bitter taste. Native to Southeast Asia, it is widely cultivated in warm regions around the world. Smaller than sweet oranges, bitter oranges have a thick, textured skin with a bright orange color. They are primarily used for their zest and juice rather than eaten fresh due to their sour and bitter flavor. Bitter orange juice is commonly used in cooking, particularly in savory dishes, marmalades, and beverages. The peel is also used to make aromatic oils and flavorings. Despite its bitter taste, bitter orange is valued for its culinary uses and distinctive aroma.
