Got a new gas grill this week for a early Father's day present. This morning my wife decided to cook a boston butt for supper. Now she usually cooks the butts in the crockpot, drains the grease and adds BBQ sauce and its pretty good. Not today, we going to cook it on the new grill. Of course I didn't have anything to use for a rub, no wood chips for smoking, no meat thermometer, none of the stuff you need to cook a smoked piece of meat. So I run to TSC, its the nearest store that might have the things I wanted. Nope, Then to Lowes, nope, Walmart, got some wood chips, a thermometer, and a grilling pan with rack, then to Ingles for some Apple juice. Could not find an injector needle anywhere. OK going to cook it without the injections juice. Lit up the grill and with my new digital thermometer, got the heat up to 275f exactly. Went to add the wood chips in their little smoke box and of course dropped the box inside the grill and had to turn off the burner to clean up the mess. Got that done and relit the burner and got the stove back up to temp. Put the meat on the grill and inserted the temp probes and started the waiting game. 2 hrs, turned the meat around, added more rub and closed the grill lid. Pulled every rookie mistake, even knowing better, but couldn't resist taking a peek every now and then. Meat turned a red smokey color but didn't crust over, and the internal temps seemed to get stuck at about 140F. I had read that might happen so I just decided to let it cook some more. About 4 hrs into the cook, it started getting cloudy. No rain in the forecast, but my weather rock was starting to get damp which means rain. It didn't just rain, it came a cloud burst, grill cooled off to 190F. even tho I was steadly turning up the heat. Internal meat temp still around 140F. Grabbed some aluminum foil and wrapped the meat and threw in the oven at 300F. about a hr later, meat temp is 198F. Done!. We opened up the foil and the meat was juicy and tender, but it wasn't pull apart ready. Ate it anyways, because I was hungry and it sliced real easy. My wife said this isn't BBQ, but she ate 2 platefulls. The Butt has a real good taste, not to smokey, not to spicy, but it wasn't pull apart-able. So what did I do wrong? Also, the thermometer on the grill lid is about 20degrees off of what the digital thermometer said it was.
