Live Butter Lettuce

Keep moisture in the clamshell for a week and a half to two weeks to make it last (if you don't eat it first).  

This is a maybe, maybe not product.  It was there last week, but i don't know about next week.

Keep the roots attached to the lettuce until you're ready to use it. If using half a head, cut off what you need and keep the rest intact. When storing in the fridge, wrap a damp paper towel around the leaves and place in an aerated plastic bag in the crisper drawer. It's best not to wash the lettuce until you want to use it, as over-handling can bruise the leaves.
