maybe because salami and pastrami are nothing close to each other. Pastrami is smoked corned beef.
That's more than a bit oversimplified (for one, wet-curing vs. dry and not boiling the living shiat out of it produces a product with a significantly different texture, as made evident by the fact that I love pastrami and abhor corned beef), but yes, thank you, I'm well aware of that.
The point is that "they're two meats commonly found on sandwiches and therefore would probably be clued in a similar fashion" is plenty close enough that it should have raised a red flag in review, especially for a category with no shortage of easy replacements.
/dammit, now I want pastrami
