About
Iceberg lettuce (Lactuca sativa var. capitata) is a cultivated variety of common garden lettuce originating in the Mediterranean region and developed into its modern compact form in the 19th century. It is characterized by a large, densely packed head of pale green, crisp leaves arranged in concentric layers around a firm heart. The leaves are mild in flavor with a subtle sweetness, possessing a high water content (approximately 96%) that contributes to their refreshing crispness. The variety earned its colloquial name from the practice of shipping it packed in ice across North America during the early 20th century.
Culinary Uses
Iceberg lettuce is primarily used raw in salads, slaws, and composed dishes, where its crisp texture and neutral flavor serve as an ideal backdrop for other ingredients and dressings. It is a foundational ingredient in classic preparations such as wedge salads, cobb salads, and tacos, where its structural integrity allows it to support heavier toppings and dressings without wilting. The outer leaves may be separated and used as cups for appetizers or wraps, while the inner leaves work well in grain bowls and mixed greens salads. Though often overshadowed by more assertive lettuces, its mild character and satisfying crunch make it a practical workhorse in both home and professional kitchens.
