Question: what is the difference between corned beef and roast beef?
Answer: Roast beef is just that: beef which has been roasted. ... Corned beef is beef which has been cured with salt and spices (often pepper, allspice, and bay leaf), then simmered in water to cook it. It's traditionally made with the brisket, which has more fat than the ones usually used for most roast beef deli meat.
