After several ideas exchange with one of my mate, I finally decided to attempt to sous-vide one of the most iconic Vietnamese dishes: pho.
Ingredients preparations.
All spices into a cheesecloth.
Dropped all ingredients in 2 separate bag. (Ox tail, bone marrow, charred onion and ginger, spices and top up with water.
Into the bath for 48 hrs @ 140.
Beef brisket cleaned and ready to go into the bag as well.

Brisket in after 24 hrs.

After 48 hrs, transfer both bags into a big pot to finish it with some fish sauce, rock sugar and little salt. Simmer the broth little before serving.
