Spanish onion
Quick Summary
A Spanish onion is a large, mild-flavored onion, typically with yellow or white skin. Onions, in general, are herbaceous biennial plants grown for their edible bulbs. Likely originating in southwestern Asia, onions are now cultivated worldwide and are valued for their flavor in cooking, adding depth to dishes like stews, soups, and salads.12
The characteristic pungency of onions comes from a sulfur-rich volatile oil that is released when they are cut, which can cause tears. Onions have a long history, with ancient Egyptians viewing the bulb as a symbol of the universe. Spanish onions are noted for being sweet, juicy, and mild, making them suitable for use raw in salads and sandwiches, as well as for garnishes.2
