About
Head lettuce, also known as iceberg or crisphead lettuce, is a cultivar of Lactuca sativa characterized by its dense, spherical head of tightly layered leaves. The plant originated in the Mediterranean region and was selectively bred for its firm, compact structure. Head lettuce features pale green outer leaves that gradually whiten toward the interior, with a crisp, watery texture and mild, slightly sweet flavor. The variety is named for its resemblance to a head of cabbage and was given the "iceberg" designation in the early 20th century due to its ability to withstand long-distance shipping when packed in ice.
Culinary Uses
Head lettuce is primarily used as the foundation for fresh salads, particularly in Western cuisine, where its crisp texture provides satisfying crunch and structural integrity when dressed. The sturdy leaves are well-suited for composed salads, wedge preparations, and as a base for salad bar applications. Beyond salads, head lettuce serves as a bed for deli sandwiches, burger garnish, and wrapping material in some Asian preparations. The outer leaves can be braised or added to soups, while the tender interior is preferred for raw consumption. Its neutral flavor profile makes it an ideal vehicle for vinaigrettes and creamy dressings rather than a flavor driver in its own right.
