Welcome to SMF and to the wonderful world of
WSM ownership! Get ready for some tasty weekends.
Do a dry run, no meat, and learn what you need to know to control temps with your vents. I half loaded mine with charcoal only, no water in the water pan, and played with the vents getting a feel for the vent settings for different temps. My experiment lasted 13 hours and I ran it from 225F up to 350F.
Foil your water pan or use a drip pan to prevent a fatty mess. For drip pans I use 9x13 aluminum pans you get at Costco cheap, paella pans with handles that I can put a round rack in; and a round aluminum cake pan I can put on the lower grate (actually haven't tried the last one yet, but I got one free that fits my
WSM and am ready to try it myself).
The easiest thing you can smoke are brats. They'll tolerate just about any temp you want to use and you can tell when they are done just by looking at them (start to crinkle a little). They respond well to both a wet smoke (water in water pan) or a dry smoke (no water). They smoke up pretty quickly relatively speaking.
Chicken is easy too. High, dry heat (dry smoke), 300F+ works best. Easy peazy to take to an internal temp of 165F.
Shrimp is a very easy smoke, takes on flavor nicely, but is pricy these days.
I love smoked meatloaf but my wife is not a fan. It is a very easy smoke. High temp 300F plus, dry smoke to an IT of 165F.
Pork butt and pork shoulder is very forgiving too and can tolerate anything from 225F on up. I foil mine at the first sign of a stall to shorten the smoke but you can leave them unwrapped until they reach an IT of 203-205F for pulling apart.
Beef cuts like chuck roasts and brisket are easy too but their tender, juicy window can vary a lot. You can smoke them like the butts and shoulders but start sticking them with a tooth pick when the IT reaches 195F to 200F. The toothpick should slide in like pushing in room temp butter.
Have fun and be sure to post pics of your first smoke.
