Defrost the rolls and glaze at room temperature for 15 to 20 minutes. Meanwhile, preheat your oven to 350 °F. Place the rolls close together on a baking sheet. Coat them with glaze and sprinkle with the caraway/salt mixture. Place coated rolls in the oven and bake them for 2 minutes. Put the au jus concentrate into a pot with one quart of boiling water. Add more hot water to adjust flavor, if desired. Defrost the all-natural roast beef briefly at room temperature until you can separate slices. When defrosted, transfer to a platter. Use tongs to pick up 2 to 3 slices of meat and dip into hot au jus for about 5 seconds. Place the warm beef on kimmelweck rolls and add horseradish and other condiments of choice. Serve with a side of warm au jus for dipping.
A spectacular sandwich unique to Western New York, beef-on-weck is roast beef on a kimmelweck roll served with au jus and horseradish. Anderson’s award-winning (and horemone-free) roast beef is slow roasted to perfection, thinly sliced, and layered on a kimmelweck roll (Kaiser roll sprinkled with pretzel salt and caraway seeds). For an authentic Buffalo experience, spread horseradish on your all-natural roast beef and quickly dip the top ‘weck bun in the au jus. Serve with a side of dill pickle spears. Finish the meal with Anderson’s signature frozen custard, made from the finest natural ingredients in small batches and hand-stirred at their store in Kenmore, New York.
