A lobster roll is a kind of sandwich filled with lobster meat. A traditional lobster roll contains the fresh cooked meat of a lobster, tossed with mayonnaise and served on a grilled hot dog bun or similar roll, so that the opening is on the top rather than on the side. The filling may also contain diced celery and/or scallion, or may use drawn butter instead of or in addition to mayonnaise. The sandwich may also contain lettuce, lemon juice, salt and black pepper. Traditional New England restaurants serve lobster rolls with potato chips or french fries on the side. As far back as 1970, chopped lobster meat heated in drawn butter was served on a hot dog bun at road side stands such as Red’s Eats in Maine, but have since given way to the chilled lobster “salad” prevalent today everywhere but Connecticut.
