24 hour Beef

 
 
I got a sous vide for Christmas 2 years ago and it was neglected for a long time. Then we had 24hour cooked beef at the restaurant Chez Shea and wondered how it was so perfectly cooked medium rare even though it was cooked for 24 hours.It took me for a while to figure it out, but I finally thought it must be the sous vide cooking. So yesterday I bought tough cut of Angus beef and cooked for 24 hours in the sous vide at 140 degree. The result was, "Yes, I was right." The beef was perfectly medium and tender. If I could make demi sauce like Chez shea, and they must have good butcher to get better cut, but it was close, at least I think so. Anyway, it was delicious and I am so happy that I could finally use my sous vide.
I made my own sauce with onion, mushroom, butter, red wine, beef stock and tomato paste and it was OK.
