Any of several varieties of lettuce (green leaf, red leaf, oakleaf) with leaves that don't form tight heads. These leafy bunches have a mild flavor that's more full-bodied than iceberg lettuce. Leaf lettuce can range in color from medium to dark green; some have red-tipped leaves.
How to Buy
Look for bunches with crisp, evenly colored leaves that aren't wilting or yellowing.
How to Store
Wash and either drain completely or blot dry with a paper towel, then refrigerate in a plastic bag up to about 3 days.
