Because asparagus is one of the most expensive vegetables in the United States at approximately $2.95 per pound, it is a good idea to know what you are looking for. First, the stalks should be straight, plump, and firm. You do not want anything limp, rubbery, or scaly and dry. The tips should be closed, compact, and close to the stem. Those that are splaying were picked too late. The color should be rich green with a white bottom. Also, avoid small or extra-large stalks.
