When purchasing iceberg lettuce, it is important to look for a head that feels heavy for its size and has crisp leaves. Avoid lettuce with browning or slimy spots, as this indicates decay. Fresh iceberg lettuce can be stored in the refrigerator, wrapped in a damp paper towel and placed in a plastic bag for up to a week. It is advisable to wash the lettuce thoroughly before use to remove any dirt or bacteria.
