Last year I rigged myself up a version of the AB flower pot smoker. I use a big old 18 terracotta pot & saucer with a cast iron hotplate and weber grate. It works fantastically. I put it together solely for pulled pork (I do some killer tacos with it).
It's not quite as user friendly as my brother in law's $1k traeger, but I spent less than 10% of what he did, and I'm a broke medical student.
I've tried a handful of things, some worked out well and some haven't.
Artichokes with crushed garlic (hickory) = awesome corn (hickory) = not good 80/20 burger, started over smoke, finished on grill = easily one of the best burgers I've eaten and I'm straight up persnickety.
The burger was dinner tonight, I'd been toying with the idea for a while, and I needed a break from studying, so I fired up the smoker with some apricot. Uh-maze-ing.
What successes have you had?
