I'm part of an international rescue team and one of the things we need to do is to be self sufficient. At the minute we take ready made boil in the bag food which is not particularly great and is quite expensive.
I recently saw Heston Blumthall proposing the use of Sous Vide food for preservation of food on a submarine and wondered if the same approach could be used by my rescue team. So the question is if the food is cooked by can it be kept on a store cupboard shelf and if it can, what would the shelf life be? I'm assuming that the quality of the packaging could have an effect. If it can how could this be taken into account?
