Beef on weck

A beef on weck (also known as beef on wick) is a sandwich found primarily in Western New York. It is made with roast beef on a kummelweck roll. The meat on the sandwich is traditionally served rare, thin cut, with the top bun getting a dip au jus and topped with horseradish.

The kummelweck roll gives the sandwich its name and a distinctive taste. A kummelweck (sometimes spelled "kimmelweck" or "kümmelweck") is topped with kosher salt and caraway seeds. Kümmel is the German word for caraway, and weck means "roll" in the south-western German dialects of the Baden and Swabia areas (northern Germans generally say Brötchen), although the kind of weck used for this sandwich in America tends to be much softer and fluffier than a standard German Kümmelbrötchen or Kümmelweck. In Austria, a similar type of small white-bread is known as Kümmelweckerl (diminutive from Wecken, which refers to a whole big bread, i.e. Brotwecken).
