I've got some smoker questions.
1- Where are you guys getting your rubs? Are you making them, buying them off the shelf locally (where?), or ordering online?
2- Same question for BBQ sauce. Do you make it, buy it local, or order online? This one might be easier because grocery stores have lots of options.
3- Are you changing pellet "flavors" based on whether you are smoking beef, pork, or chicken? What do you use for each if you switch or what is your standard pellet flavor?
4- Where do you go for recipes on things you haven't tried before? I've been watching All Things BBQ, Meat Church for Traeger, and How To BBQ Right videos on youtube. Is there a go to resource? I have to say I like Chef Tom on ATBBQ the most.
I have had a Trager for 4 or 5 years now and have tried all sorts of stuff.
If you watch most the rubs or directions for dry brines follow approximate ratios. For my goto rub for pork shoulder, for example, I typically go equal parts Kosher salt and brown sugar, then throw in a healthy amount of garlic powder, paprika white and black pepper, cumin, and chili powder in order of the amount. But the Salt and Sugar ratio is the most critical everything else is pretty minor.
Before buying a bunch of expensive rubs, I would go to Costco's spice aisle and grab whatever sounds good and try it out.
I buy R&R's BBQ sauce because I haven't dabbled in making my own too much yet that I like it more than theirs. I especially like their Carolina sauce for pulled pork.
I typically mix hickory, maple, and pecan, and use it on everything. But I probably don't have all that sophisticated of a palate that I would know the difference.
I used the traeger online recipe page, the Smokin Word BBQ page for ideas on what to cook, and always watch a few different Youtube videos before I try anything new and then try to just take the general principles and experiment in variations with what makes the most sense to me. I'm not one that ever follows recipes exactly.
