Well, you're in for a treat: check out the writeup I did for Serious Eats about the Jumble, one of the first cookies that made it over to the US from the old world. Jumbles originally gained popularity because of the fact that they kept amazingly well on sea voyages (although undoubtedly they became pretty dense and rocklike by the end of the trip!). These days they've evolved into a soft, moist drop cookie with unlimited flavor variations. You can more about one of our nation's oldest cookies--as well as get a delicious recipe for a soft, spicy, frosted version (complete with mini candy rocks as a shout-out to Plymouth Rock!), on Serious Eats!
