Bibb or Limestone Lettuce

Similar to Boston lettuce, but smaller and more delicate. A whole head may be only a few inches (less than 10 cm) across. Color ranges from dark green outside to creamy yellow at the core. Its tenderness, delicate flavor, and high price make it a luxury in some markets. The small, whole leaves are often served by themselves, with a light vinaigrette dressing, as an after-dinner salad.
