Bear, you said you seasoned with just pepper, garlic and onion powder. Did you not season it with any salt? Just curious, as usually I salt the meat before sous vide, but maybe due to the long cook time you salted it afterwards?
I used to use salt, but on Nov 8, 2012, a Stupid "Dr" screwed up & caused problems inside me, including wrecking my Kidneys.
So that, along with my High BP, keeps me from using much Salt. If anybody wants salt, they can add it at the table at my house.
