This video shows you how to make one of the United States' most delicious unknown sandwiches, the Beef on Weck. This is Part 1, which is all about the delicious freshly baked kummelweck roll. The roll's fragrant caraway seeds and coarse salt are a perfect accent for the thinly sliced, horseradish-covered roast beef. Watch the video, then get the recipe for Chef John's Kummelweck Rolls. Enjoy this sandwich with a ramekin of steaming beef jus. You'll understand why this is the pride of Western New York.
