Leek scapes are long, slender green stalks with light green or yellow bulbs near the end with tips that taper to a point. The scapes are harvested once the flower pods have developed and while the stems are still pliable and tender. If left to grow they will toughen and produce large purple pom-pom like flowers. Leek scapes offer a mild garlicky aroma and a mild allium flavor, with an asparagus-like texture.
