I’ll be cooking a prime rib roast (aprox 7 pounds, no bones) on Christmas day. I’ve seen a bunch of diffrent times on the internet, ranging from 6 hours to 24 hours. Has anyone had any experience cooking prime rib with the Anova? Dinner is at 5pm and I wan’t to know how early I’ll have to get up to actually have it cooked by then. Thanks ---
