Sweet onions are a variety of onions typically harvested young, when their bulbs are still small and tender. 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.
