Juice oranges, originating from Valencia, are a highly valued variety for their sweet and refreshing juice. Generally medium or small in size, they stand out for having a thinner, yellower skin than table oranges and are characterized by not having a navel. These oranges contain less fiber, making them ideal for producing delicious juice. In the kitchen, they are a versatile ingredient that can be used in countless recipes, from custards to cakes. Some useful tips include storing them at room temperature to preserve freshness, although refrigerating them can help prolong their ripening process and maintain quality.
