A vegetable and/or salad leaf comprising a white bulb of tightly packed elongated cones of overlapping white leaves with pale yellow leaf tips. Although we call it chicory here, it's more commonly known as witloof (meaning white leaf) in Belgium and is called Belgian endive in the US. It’s essentially a salad vegetable with a mildly bitter taste, but it can be cooked too. It's particularly good wrapped in ham, covered with a béchamel sauce and oven baked.
