Had a near disaster over the weekend. I was tossed a big fat rib eye in the cooker, set it for 128 and made a run to the store. Came back about an hour later and noticed the temp on the cooker said 145!
Pulled it out and tossed it in ice water while I investigated. Temp was set for 128, but temp was 145. Had to unplug the cooker to get it to work again. Fortunately, the steak started frozen, and was a decent medium-medium rare, so not quite ruined. I won't be placing much trust in this Anova for a while...
