I'm going to save you some time and put my favorite part of the article right here: “We narrowed it down to a few parts of the animal, and some of them are unexpected.”
Um, what? Exactly what parts of the animal would be used in this cut of beef that would be characterized as "unexpected"? Why do these unexpected parts of a cow bring out the flavor of beer? (Whoops, just threw up in my mouth a little bit thinking about it). And how exactly does beer make the unexpected parts of a cow be at their "best"?
What Sam Adams, or even better...the makers of grain alcohol...should be doing is coming up with some drink to bring out the best of fish and shrimp contaminated with the flavor of crude petroleum. Now THAT would certainly be "unexpected"!
