Sweet onions from Castilla León are prized for their mild flavor and lower pungency compared to regular onions. This is due to their low sulfur compound content, making them ideal for eating raw, especially in salads. Proper storage requires keeping them in a dry, cool place to maintain their organoleptic qualities. In addition to being eaten raw, these onions can be cooked in various ways: roasted, boiled, sautéed, or fried. They make an excellent accompaniment for meat, fish, vegetable, or legume dishes, and can also be used in tortillas or as part of sauces for fillings. With low-calorie content due to their high water content, these onions are a healthy and versatile option in the kitchen.
