Red Butter Lettuce is like its green bibb or "butter" lettuce counterpart, except with reddish leaves. The loose, delicate, tender leaves have a buttery flavor and make for some delicious salads. When you handle bibb lettuce, do so delicately, as the leaves can easily bruise.
To prepare, remove the core and then immerse the leaves in cold water, drain and pat dry, or run through a salad spinner. Bibb lettuce leaves are popular in tuna and salmon salads in many places, but are also used to add flavor to raw vegetable salads.
Do not store greens on the counter top unrefrigerated, or just throw them on a shelf in the fridge! They will surely wilt and go bad quickly. DO wrap lettuce or greens in a dry paper towel and place in airtight container or plastic bag in the fridge. The paper towel will absorb any excess moisture that makes the lettuce rot and will keep it fresher for much longer.
