This was a lean venison roast which was new to me. Made the mistake of following the first set of directions I found online and should have realized it was 2-3x too long. The recipe for some reason said 12-14 for a 2 ln roast which is very obviously incorrect in retrospect. Embarrassing, but now I know what the consequences can be when you really overdo it. Had always wondered

Ah, that stinks. Venison was a staple growing up, but I’ve never sous vide’d it. Do you have a machine or what? I use a trough heater, temperature probe, and cooler. Did 60 chicken breasts once in a big cooler. So nice having prep grace time. 
We have a joule that someone gifted to us a while back. I’ve heard Anova is the brand to go for if you’re ever buying one!
