They are known for their mild, sweet flavor and are often favored in salads, sandwiches, and other dishes where a milder onion taste is preferred. These onions are characterized by their white, slightly elongated bulbs and green stalks that are also edible and add a fresh crunch to dishes. Bunched sweet onions are popular in both home cooking and professional kitchens for their versatility and pleasant taste profile.
