Step 1

Preheat water bath using immersion circulator to 165 degrees F.

Step 2

Cut rib racks in half (you want 6-10 inch wide pieces) so they're easier to vacuum seal and will fit better in your water bath. Season liberally with BBQ seasoning. If using a salt-free seasoning, season with kosher salt as well.

Step 3

Vacuum seal each piece of rib separately.

Step 4

Cook in preheated water bath for 12-16 hours. If using baby back ribs, closer to 12 hours. If using spare ribs, closer to 16 hours.

Step 5

When done, remove from water bath. At this point, you can refrigerate until ready to finish or finish immediately. Brush with BBQ sauce before finishing. To finish on the smoker, smoke at 175 degrees F for 2-3 hours. To finish on the grill, grill over high heat for about 10 minutes each side, until browned. To finish under the broiler, line a rimmed baking sheet with foil and place ribs on sheet. Place under broiler for about 5 minutes on each side, until browned.

Step 6

Brush with more BBQ sauce if desired and serve.
