Hey everyone I love iceberg lettuce when I am making sammiches and burgs at home - it is cool, and sweet and just the perfect neutral accompaniment with a lot of things. But I do feel it's missing something - you can go to some places for a schnitzel sammich, and the sweetness of the iceberg lettuce almost has a vinegary taste to it. Is it just because the lettuce is sitting in water to keep it fresh? Or do they add something to it? What is the secret?!
