Compared to other onion varieties, Spanish onions have a sweeter and less pungent flavor, making them ideal for cooking and caramelizing.
The unique flavor profile of Spanish onions is due to their low sulfur content, which is responsible for the pungency and tear-inducing properties of onions.

Additionally, Spanish onions are often used in traditional Spanish cuisine, such as in paella and gazpacho.
