Oh yeah, I have been doing that for years. It helps on so many ways.Think about slathering the butts with mustard and then the rub.
I have done that a few times. I was looking for something new to try before I remembered I had the Joe's Kansas City run in the cupboard that I had not tried.You can also make your own rub (plenty of recipes on here) a tweak it to your taste.
I might try that next time. Before things ended up on the ground on Wednesday it was a pretty easy smoke with the pellet smoker. I have another butt in the freezer and I am watching the local groceries for some sales so I can do this a few more times over the summer and try some different methods.Good luck on the cook today. I typically don't put mine in pans until I wrap around 6-8 hours. I put them in pans with a little apple juice wrap them tight and into the oven and I bump the temp up when I put them into the oven. Pleanty of juice and bark
