Also called sand leek and giant garlic, rocambole has leeklike bulbs that taste like mild garlic. It grows wild (and is sometimes cultivated) throughout Europe and may be used in any way suitable for garlic. Rocambole is rarely commercially available in the United States but might be spotted at farmer's markets.
