I agree Chris, that sounds like a horrible combination. Why not try that on a niece cut of pork instead?

Well you obviously can't taste every possible combination of flavors, so typically you'd use your mind to mentally picture the flavors together and try to get an idea of whether that would give you a good result or not. For example, I've never tried groundbeef mixed with pureed strawberries, but I don't feel the need to try it to see whether or not it tastes good, I can mentally imagine the two flavors combined and know that's not something I'd enjoy.
Having said that your mind can sometimes trick you and some flavor combinations that you would never have thought would work can actually surprise you. When I was in Molokai they had this tangerine based marinade we used on everything including steak, and it was absolutely to die for. Go figure.
I rarely marinate beef, but when I do I try to keep it short. The longer you marinate, the more it will have the taste of the marinade, but the less it will have the taste of the beef, so you have to find your balance. Personally I think 8 hours would be insanely long for a steak, especially with something like apple juice which would start cooking the steak while in the fridge! I wouldn't consider more than 1 to 2 hours depending on the size of the cut.
If you end up doing it let us know how it turns out!
