We were asked how to best keep the greens from wilting.Wilting is a result of dehydrating. We suggest to put the cut ends in water standing up and then a plastic bag over the top to keep them from dehydrating (or a crisper drawer). We keep it in our cooler for upwards of a week.
Lettuce is best stored in a cloth bag – like a cotton bag. Do not clean it until you are ready to eat it – that is what turns it into mush.
