I used to always spend ages stripping and washing lettuce as I am concerned about bacteria that gets on the leaves when they are picked by hand. There have even been recent reports about all sorts of nasties getting on the outside. I have started to strip the outer leaves and cut off the stem so we only eat the heart of the lettuce which has not been touched. I feel that washing bugs and bacteria in water just wont kill any nasties. This works easy with Iceberg as not much is wasted, Romaine is more difficult, what do you do, wash or not?
I do not like to use the sanitised bag type as I feel it just does not taste the same for some reason.
