Jumbo onions are large, firm bulbs with papery skins and a robust, slightly sweet onion flavor. They are versatile in the kitchen—suitable for slicing, dicing, caramelizing, roasting, and grilling. Use them in sautés, soups, salads, sandwiches, and burgers. Store in a cool, dry, well-ventilated place away from direct sunlight to maintain freshness and flavor. Ideal for both home cooks and professional kitchens.
