I'm going to give this a try tomorrow. Got a sirloin tip roast (just over 4 pounds) marinading overnight using a variation of the rub putty:
1/2 cup Wegman's Kansas City BBQ Sauce
1 1/2 tbsp honey
2 tbsp peach jam
1/2 oz. Jim Beam
I didn't have any grape jelly, but I figure peach and bourbon is a good combination, soooooo...
Rubbed it with Big Green Egg Sweet Maple Seasoning, and into the fridge overnight. I think I'll try smoking it at 225 F until it reaches 190 F internal, then foil it and into the oven for a little while, then I'll pull it.
Anyone have any idea how long - roughly - a 4 pound sirloin tip at 225 F might take to reach 190 F internal? And will spritzing it with a bit of apple juice (every hour, maybe?) be a good idea?
