We have a local favorite steak here in the bay area called “Fred’s Steak” which is a secret marinate on a tri-tip sold by a local family run butcher shop. Traditional preparation is either grilling or baking. But sure enough, a sous-vide treatment (45 to 60 minutes at 128-135 depending on taste) followed by searing in an iron skillet (or with a torch) worked out great and has won hands down in blind taste tests we’ve run here.
I’ve done the same thing with tri-tips prepared several different ways. Another winner for the sous-vide cooker!
