I was looking for roast beef, but i only found pastrami. There is any difference between them i mean in their flavors or is almost the same.
Pastrami is prepared in the same way but is smoked after curing.
Roast beef (also known as a roast) is a cut of beef which is roasted in an oven. Roast beef is often served within sandwiches and sometimes is used to make hash.
Pastrami is heavily spiced with black pepper and other things. I think it only comes in slices (whereas roast beef is available either sliced or uncut). I don't know if there's any other differences.
Hayyim's got the basics of it down , the only thing I'd add is that pastrami is cured/smoked.
Ah! Thanks, I suspected I was forgetting something.
