Originating from the esteemed Jewish delicatessens of New York City, the Reuben sandwich has traversed the United States, becoming a beloved classic in its own right. This hearty creation has also found its way into the realm of cocktail appetizers, served in miniature form. While the choice of bread sparks some debate, with opinions divided between pumpernickel and rye, there is unanimous agreement regarding its delectable contents. Tender corned beef and Swiss cheese embrace a moist interior of sauerkraut mixed with Russian dressing, creating a symphony of flavors within. The sandwich is then carefully broiled, reintroducing controversy surrounding the decision of whether the cheese should be melted during this process or if the interior should retain a refreshing coldness.
