Did a Sous Vide flank steak for the first time. Smoked at 180F for about an hour, then SV at 135 for about 5 hours, then chilled in ice water. The following day I seared - had planned to sear on cast iron griddle but forgot to put the griddle into the grill, so seared on the grates. Not as a good of a sear as I would have liked, but still very tasty. The most tender flank steak I've ever eaten.
