Red-Leaf Lettuce
Description
Red-leaf lettuce is a vibrant, burgundy-colored leafy vegetable that is a variant of the Lactuca sativa species. Its leaves are tender and mildly flavored, making it a popular choice for adding color and nutrition to a variety of dishes. Red-leaf lettuce is similar in shape and texture to green-leaf lettuce but boasts a richer hue that ranges from deep red to purple, often with green at its base. It is commonly found in grocery stores and farmers' markets, often sold as 'red oak leaf lettuce' due to the oak-like shape of its leaves.
Common uses
While red-leaf lettuce can be used in any recipe calling for leaf lettuce, its striking color is particularly prized in raw applications where its appearance can be showcased. It is a common ingredient in salads, sandwiches, wraps, and garnishes. Red-leaf lettuce can also be lightly wilted and used in warm dishes, though its delicate texture is best preserved when used fresh.
