I bought a beautiful bunch of green leaf lettuce Sunday. Monday it was still nice and fresh. When I got it out of the crisper for lunch yesterday, most of the outer leaves had frozen! It wasn't very wet when I put it away Monday, but there was enough moisture to make the leaves freeze. I have a humidity control on my crisper with 'high' and 'low' settings...but I dont know which one to use. 'High' has all of the air holes on the crisper closed and 'low' has them all open. I had it on 'low' and changed it to 'high' yesterday.
What is the proper way to store lettuce? Am I supposed to wash and spin the entire head before storing? Do I need to wrap it in something? I can't afford to keep throwing food away because I don't know what I'm doing! Any suggestions will be appreciated!
Thanks!
