White Asparagus with Arugula

White asparagus, usually considered a delicacy, has a very short growing season, and is typically seasonably available in May or June. It is white because it is grown without light, thus keeping the plant from producing chlorophyll, which gives it its usual green color. White asparagus is milder in flavor, though it still has tough stems that should be removed before cooking. This dish pairs especially nicely with salmon for dinner, or smoked ham such as Westphalian ham or prosciutto for lunch. Dill and asparagus are a wonderful combination of flavors.
