Fairway is carrying a variety of greenhouse grown lettuce with roots still attached. The "butter lettuce" comes in a see-through container, so you can actually see the roots and the quality of the lettuce inside. Gothamist has seen this before with delicate lettuces like mache, but a whole head of lettuce with roots was a first for us. After bringing it home and making a salad with it, it was very fresh and convenient to use, as you could just rip off the lettuce you need and let the rest of the leaves stay in their roots. Gothamist wasn't sure it tasted any fresher than a regular head of lettuce, but it seems like it will last longer than bagged, loose lettuce leaves.
Has anyone else tried live lettuce?
