Does \"the canned spinach taste\" have a name? Other than \"the canned spinach taste\"? References The taste (which is nasty in my opinion) that is specific to spinach or many leafy greens and sometimes asparagus which is cooked in water, does this taste have a name? What causes that flavor to emerge? I suspect its something to do with chlorophyll since dried basil added to sauce doesn\'t produce the flavor, yet fresh basil does. I added fresh basil to sauce to which it gave the flavor of canned spinach.
