Many people don't realize that the Martini was originally made with sweet vermouth. The recipe shown here, would have been what you probably would have gotten had you simply ordered a "Martini" in most American bars around the 1900's. You may want to experiment a little bit with the ratios since which gin you use, as well as which sweet vermouth, will present a different flavor profile. This drink should be full of flavor, but it shouldn't taste overly sweet.
