Raye’s Mustard Mill Museum is a working stone-ground mustard mill and mustard shop in Eastport, Maine that moved to that location in 1903. The family began making mustard to compliment the local sardine industry. They’re “the last remaining traditional stone ground mustard mill in North America” and have exciting mustard gift baskets!
Speaking of sardines, there is a Sardine Museum [and research] in Lubec, Maine — travel from the mustard museum either 38 miles by car, or only 4 miles by boat.
