Since I am taking over cooking for the day anyway, might as well go for it!
8# of babybacks from Costco. I have had nothing but great luck with these ribs from Costco, they come wither blister packed or in the traditional foam and plastic wrap. They are de-membraned and ready to go right from the package. Prices have jumped a bit though lately.
Normally for 7-9# packages there are 3 racks, but the 8# today had only two as one was HUGE, must have been a Hogzilla, easily double the mass of normal. Seasoned up and waiting for start-time.
Also going to smoke up a couple potatoes for twice smoked potatoes.
