While lamb makes up only a fraction of the meat eaten in the United States, it is used in a myriad of wonderful recipes throughout the world. When lamb is labeled as "spring lamb" it signifies that lamb that was brought to market during the spring and summer months which was formerly the season for fresh lamb. However, lamb is now available throughout the year, and the label "spring lamb" does not necessarily connote additional quality. Lamb is the meat from young sheep that are less than one year old.
