I found a couple racks of ribs at my local supermarket, two for the price of one, so despite being pre-rubbed and seasoned, they were only 7.20 a rack. As had been pointed out, they do have smoke flavor added, but that doesn't mean I can't smoke it myself too.
The smoker used is an electric smoker I got from my local Aldi for 80 bucks. For only 80 bucks, it's been reliable, and delivering of lots of tasty food.
The wood used is willow wood I cut into strips myself. This came from a branch we cut down from a tree in our back yard, of which I saved a few pieces for smoking. As a wood I'd compare it to be similar to maple wood, not particularly harsh, but it's still a very flavorful wood, beyond something like apple.
I did nothing to the ribs until they had cooked a while in the smoker, at which point I applied some hickory flavor Ray's no sugar added barbecue sauce. Everything just as simple as can be.
The sides, as seen in the last picture, are hash browns (frozen from a bag, done on a sheet pan in the oven) and box mac & cheese. The result is as good as it looks, the ribs even had a bit of bark on them. Total smoking time was around four hours, two at 175F, one at 200F, and one at 230F (roughly)
