my lovely sister,
In early 19th-century New England, molasses was relatively easy to come by. As a byproduct of the slave-powered sugar refining industry, molasses was essential to making rum, a valued trade commodity. And in most seaport towns, molasses-based booze and baked goods went hand in hand. Marblehead, Massachusetts, has been known for its rum-and-molasses cookies, nicknamed Joe Froggers, for centuries. But the exact origin of these treats is a bit of a mystery.
