Sous Vide Pork Loin


When I cook, it’s usually just for my wife and myself.  Because it’s just the two of us, we have to scale things down a bit, lest we have enormous amounts of leftovers.  But sometimes it’s advantageous for us to buy certain things in bulk and then portion them up for multiple uses.  Pork loin is one of those things – Heather will buy a large pork loin from Sam’s Club, and I’ll part it in half. 

This past weekend, I decided that pork loin sounded like a great option for dinner.  With plenty of time in the day to cook it, this made sous vide + grilling the pork loin a very attractive option.  How I cooked the pork loin is outlined below.  Once again, I turned to my reliable SousVide Supreme sous vide machine.
