Set the sous-vide temperature to your desired doneness. Remember that the searing process will raise the internal temperature of the food. Depending on several factors, this can be significant. Consider choosing a sous vide temperature one level below your preference - rare for medium-rare, medium rare for medium, etc.
Once the water bath has reached the desired temperature place your burger patties in and close the lid. Allow them to cook in the circulator for 1 hour. You can leave them in up to 4 hours.
