Romaine Leaf Lettuce or cos lettuce
(Lactuca sativa L. var. longifolia)
|With its tender taste and health benefits, romaine lends itself to salads (on its own or mixed with other greens), wraps and sandwiches. Select heads with crisp, fresh leaves without brown stems. Wash and dry thoroughly on paper towels before storing in a plastic bag in the refrigerator crisper for up to one week. To crisp romaine, plunge the leaves in ice water for a few minutes just before serving.
