Just had two failures and one success. Cooked a Dexter tongue for 72hrs at 56c and the texture was just horrible, would do higher temp for a shorter time (should have listened to Jack). Tried to make pastrami excellent texture but too salty, so not the sous vide techniques fault. But the stellar result was the Dexter cheeks. Reduced bottles of Oz Shiraz & Cab Sav respectively and a half a bottle port added frozen demi-glace and 0.4% xanthum, browned the jaccarded cheeks. Vac packed and cooked at 56c for 72hrs. Unctuous sauce and perfectly tender cheeks. So, thanks to the usual suspects. Served with pomme puree and roasted veg.
