Do you need to put the roast in ice water in the fridge to bleed it out for a 2-3 days prior to marinating it? Does this really do anything or can I just marinate it for 2 days then smoke it? I plan on putting some rub on it and putting a few cloves of garlic into the meat too. What IT should I smoke to for just slicing or making sammies? Any advice or tips would be greatly appreciated.
