OK those in the know, a RD USDA Select, yeah I know Cheap Screw, 1 1/2" Rib-eye steak. Going to sous vide at 125°, then three 1 minute turns on grill. How many hours at 125° to be tender? I am starting it in about 15 minutes. If it is more then 8 hours, will have to try again later as that is all i have today.
