Sweet onions are known for their mild, delicate flavor and high sugar content, making them perfect for raw or lightly cooked dishes. With their crisp texture and low pungency, they add a pleasant sweetness to salads, sandwiches, and salsas. When caramelized, they develop a rich, golden-brown color and a deep, savory-sweet taste. These onions are typically round with pale yellow or white skin and are a favorite for gourmet cooking and fresh preparations.
