How Can I Tell If Meat Has Been Brined? My wife and I were eating some rotisserie chicken the other night and she commented something to the effect of "I think they brined this because I can taste the seasoning pretty deep in the meat."

I she probably right?  Is there a surefire way to tell if what you're eating has been brined? Perhaps by telltale marks or coloring?
Empirically, you could use a salinity meter-- one that is made for checking salt water fish tanks. The only other thing I can think of that would drive seasoning into the meat would be cooking in a pressure cooker. I believe some grocery stores employ such a method on chicken before finishing in a rotisserie. Certain fried chicken chains also deep-fry in a pressure vessel which could yield similar results.
