The previous times we slow-roasted a pork shoulder, the smoke alarm went off well before the skin crisped. We’d drained the drippings from the pan before crisping the skin, but the residue still smoked up a storm; this time we we left the pool in place to see if it kept the surface cooler and reduced the smoke.
Well, no, it didn’t. This happened in the five minutes between one rotation and the next:
Knowing things would get at least a little smoky, I’d closed the pocket door (on the left) and hung a beach towel across the opening into the laundry room (to the right), which kept most of the smoke out of the rest of the house. The smoke detector in the laundry room didn’t go off until I walked through the towel, so my precautions worked pretty well.
Wow, was that skin crispy:
Plenty of smoke and no fire; the roasting pan has narrow slits for that very reason. Took a couple of hours to vent the house, during which the yard smelled downright yummy.
Next time, we’ll plunk the roast on a lined cookie sheet (with a rim!) and see what happens.

Two words, Ed: Weber Kettle.
You can smoke up your backyard to your heart’s delight. And make the neighbors hungry at the same time :-)
BTW, is that an IR thermometer on the side table by the stove?
This one wasn’t supposed to be smoked! Next time we could crisp it in the propane barbie, although I’ve never been happy with the thing’s (lack of) temperature control.
Of course we use an IR thermometer in the kitchen. Doesn’t everyone? [grin]
One summer, we tried doing our gluten-free pizza in the propane grill. I cut a couple of 12 x 12 porcelain tiles to act as pizza stones, but temperature control was the killer. The GF crust is really sensitive to temperature and moisture variations, so we went back indoors where we could control the temp at least.
We do burgers and country ribs (precooked in water), and grill zucchini when the garden has a bunch.
