The Sweet Onion is a type of onion known for its mild flavor and high sugar content. Unlike regular onions, which can be sharp and pungent, sweet onions are often used in salads, sandwiches, and various dishes where a less intense onion flavor is desired. They are typically larger and have a lighter color, ranging from yellow to white. Popular varieties of sweet onions include Vidalia, Walla Walla, and Maui. These onions are usually grown in specific regions, which contributes to their unique taste. Sweet onions are often harvested in the spring and summer, making them a seasonal favorite for many recipes.
