This produced the best steak I have ever made. A perfect medium rare. I used a 140 degree F bath with a cold steak. I left it for two hours in the Igloo Playmate cooler. The final temp was between 130 to 135 F after searing. Next time, I am using a 130 degree F bath and going for a rare steak. Hoping for around 125F.
The steak was VERY moist. The texture was so much better than just grilling straight up. FWIW.
