Keeping lettuce fresh

A few posts ago I wrote about Boston lettuce being packaged with its roots as a way to keep it fresh longer. It's working. But, you can't always get a head of lettuce attached to its roots. And Boston lettuce can be pricey. What if I just want some romaine or red leaf? Luckily, Jeremy at Generation X Finance posted his method for keeping lettuce fresh for a week. I was very excited to see this since I don't eat salad precisely because the lettuce usually goes bad before I've finished it. The secret is keeping moisture away from the leaves.
