Should Meat Be Cooked From Raw Or Previously Sealed?

We received the following question in the “Ask the chef” section:

To cook the meat, can I place it in the vacuum bag with onions, carrots, wine, etc.? Should I sear the meat and the vegetables beforehand?

This was the answer given by Enrique Fleischmann.

It depends on the taste and the final result that you are looking for. Meat can be cooked from raw, with aromatics and vegetables inside the bag, to be subsequently seared and finished on the griddle, if thus desired. Or it can be seared, left to cool and then placed in the bag to cook the already seared meat. Both ways will give a different flavour, but both methods are functional. I would recommend cooking the meat and then sautéing it or searing it before eating.
