I used to believe that American cookies were the same as English biscuits.

Then I saw an AOL "cookery hints" feature that offered advice on what to do if your cookies weren't soft! Advice like putting them in a container with some slices of apple!
English biscuits should be light and crisp. Putting them anywhere near anything moist would make them inedible (with the exception of an EXTREMELY quick dunking in a cup of tea before eating, just enough to soften the outside but leave the inside still crisp).
