Where is lettuce best kept?
However, it can be kept fresh for longer if you wash it and put it in an airtight container with a sheet of kitchen paper. Alternatively, you can wrap the lettuce in a cloth moisturised with well-diluted vinegar, to which you can also add a little lemon juice, and put it in the crisper drawer. This will slow down the loss of nutrients for three days. Lettuce that has already been washed should not be stored together with fruit or vegetables which release ethylene (e.g. tomatoes, apples, bananas).
Tip: If salad or vegetables are already a bit old and slightly shrivelled (such as carrots or radish), leave them for an hour in water – this refreshes them.
