Butterscotch was originally used as a lubricant for carriage axles in Sweden in the 1740's. Shlimengong, as it was known at the time, fell out of favor during the summers when flies would begin to congragate under carriages. One day, when it was particularly hot out, a local confectioner got some of the shlimengong on his hand while working under his carriage. Upon accidentally licking his hand, he decided that shlimengong could be put to far better use if he added some butter to the sticky sweet conconction. Butterscotch was born...To this day, axles are squeeky in Sweden.
