This New World bean was named for Lima, Peru, where it was found as early as 1500. There are two distinct varieties of lima — the Fordhook and the baby lima (and Fordhooks are not adult baby limas). Both are pale green, plump-bodied and have a slight kidney-shape curve. The Fordhook is larger and plumper than the baby lima. It also has a fuller flavor than its smaller relative. Fresh limas are available from June to September. They're usually sold in their pods, which should be plump, firm and dark green. The pods can be refrigerated in a plastic bag for up to a week. They should be shelled just before using. Frozen lima beans are available year-round and are labeled according to variety (Fordhook or baby). Canned and dried limas are usually labeled "jumbo," "large" or "small," a designation that relates to size and not variety. In the South, dried limas are frequently referred to as butter beans. When mottled with purple they're called calico or speckled butter beans. A traditional way to serve limas is with corn in succotash. They're also used alone as a side dish, in soups and sometimes in salads. Lima beans contain a good amount of protein, phosphorus, potassium and iron. The lima is also called the Madagascar bean.
