I agree without a double-blinded test you can't know, and science would require multiple tests.. but that would be unethical. I expected it to taste bad, as did the other guy who took some home. I noted how good it tasted, and then later when we met again he, without prompting, said it was the best lamb he ever had. So that is not double-blind, but better than just my word on it.

I always heard it was the adrenaline, that it tainted the meat, made it taste bad. Arbitoirs here talk about how they use techniques to lower the stress on the animal first, even to the degree of killing them in a dark room. So I was really suprised.
