Well, Sir – I guess you didn’t follow the very first answer in the Q & A here. My guess is your handling introduced some bacteria.
HOW CAN I ENSURE THE BEST POSSIBLE SEAL AND BOND BETWEEN THE BEEF AND THE UMAI DRY® MATERIAL?
It is very important that the entire surface of your strip loin, rib eye, or top butt/sirloin be coated with the thick, sticky proteins, just like when it is first removed from the vacuum packing in which your beef supplier received it. Do not rinse, wash or dry the surface of the beef. If your beef is wiped dry, you will have less successful sealing and bonding of UMAi Dry® material. Furthermore, you may introduce contaminants or bacteria with such a “cleaning” process. When possible, purchase your strip loin or rib eye in the vacuum packaging.
