Hi Namerif! Being totally new to the "smoking business" is not a bad thing! No nasty habits to break, now that you own the best smoker out there!
First thing....slow down and
breathe! lol. There's soooo much info out there on our hobby (addiction?) that it can certainly be overwhelming! I recommend searching the recipes on this forum and find one that suits your taste. Then, get the supplies, follow the instructions, and dive in! Simple as that...there's really no better way to learn BBQ than by
doing it! You don't need lots of books to get started - just pick a recipe and go!
I would recommend a pork butt to start (Boston butt cut pork shoulder) for pulled pork. Very forgiving, and you'll learn a lot about your smoker! Every time I use mine, I learn something. But, I now have a pretty good understanding of what to expect. Just takes lots of smokes and time.
One thing you'll love about your new smoker is the simplicity! These aren't allowed in BBQ competitions because they would be an unfair advantage! Prep your meat, load the smoker with wood and a water pan, put the meat in, set the temp and forget about it until close to being done!. Yes, that simple. The complications come in when we put them on ourselves with recipes, wood choices, times, etc.
Check out the recipe section, find one you like, and don't forget to ask us any questions! Anybody can be a great BBQ chef with a Smokin-It! ;D
