White asparagus is not actually a special variety of asparagus. It is grown in the ground covered with sand or soil so it does not receive the sunlight needed to develop the chlorophyll that gives green asparagus its color. White asparagus tend be milder and more tender then green asparagus. I found that adding both sugar and salt to the water and boiling it for about 5-6 minutes was perfect. The brown butter is an excellent accompaniment to the white asparagus. Hope you like it!
