Iceberg lettuce, also known as crisphead lettuce, comes in large, round, tightly packed heads with tight leaves that range in color from medium green outer leaves to pale green inner ones. It has a bland, mild flavor, making it the most popular salad green.
How to Buy
Look for solid, compact heads with tight leaves.
How to Store
Clean iceberg lettuce before storing. Remove the core by striking the cord end of the head against a flat surface, then twisting and lifting out. To rinse, hold the head, cored end up, under cold running water. Turn right side up to drain. Refrigerate in a plastic bag up to 2 weeks.
