Howdy! i have just moved from VA to NC and in the move and doing everything i had not had the chance to fire up the smoker...until Saturday. Where i live now we have a Sams club which i joined and found beautiful piece of Sirloin Tip Roast and i thought that would be good on the smoker. So i put it and a brisket on the smoker together and a smoking we were doing! I decided to go with some simple flavors....SPOG(salt pepper onion garlic) on my beef. for the salt component i used Worcestershire sauce and soaked it rubbed it over night and this is what is looked like in the morning... After that i got my fire going with some cherry and later apple wood (was all i had) I used my new probe thermometer for the first time and watched the temp really carefully because i know the meat can get over done in a hurry. For med rare I read to take it about 130 and let it rest but my wife doesn't like hers med rare....she likes hers more medium so i took it to 138 (smoked for 2:15 @275 deg) And then i covered and let it rest for two hours. I didn't take the IT again but if i had to guess i was 145-150 or so. When i was done letting it rest I sliced into and had a taste... I ate it for lunch and dinner Saturday and lunch and dinner Sunday. I have to say it was really freakin' good. Here is what it looked like on Sunday for Dinner.... I did take a couple of the wife's pieces and sear them off at the edge on a really hot skillet. I did one of mine too that way to try it, wasn't bad but not as good as the med-med rare when it was done smoking. Well that was my smoking a sirloin tip roast last week end.
