Let us teach you how to make it last
LET lettuce last past a month!
Take a big piece of aluminium foil, preferably the extra long version, but if you can’t do that, then just use two pieces of aluminium foil to cover the entire head of lettuce.
Wrap it tight and make sure it’s completely covered. Now put it in your fridge. Yep, that’s it, it will remain just as crispy as you first did it.
