I ordered a MES 30" and a AMNTS. To make a long story short my MES was delayed do to weather. Here's my problem I bought 8lbs of top round, cut it and marinated it Wed. at 3:00 pm, my smoker should have been here on Fri. but now its going to be Mon. Well after that long winded explanation my question is how long can you keep the meat in the marinate?
