Iceberg

Iceberg lettuce, or crisphead lettuce, forms large, round, tightly closed heads where the leaves grow closely together. The color varies from medium to dark green, with the inner heart leaves being lighter in color. Iceberg lettuce has a high water content, which allows it to stay fresh for longer and provides a cool and crisp texture.

Iceberg lettuce is indeed a California creation. Due to the climate in California, these lettuce heads used to be transported while being chilled, which is how they got their name “Iceberg.”
