An Uninterrupted Supply of Sustenance
Due to the fact that submarines are required to remain below for extended periods of time, the availability of food is a big concern. When fresh food runs out in a matter of weeks, chefs are pushed to adapt in order to keep their customers satisfied. Dry items, like lasagna, can be used to construct meals that are both delectable and refined.
If perishable items are stashed away in discrete areas of the home, such as cabinets, pantries, and closets, the shelf life of such items can be prolonged even further. It is possible that fresh foods will keep their quality for a longer period of time in the ocean than they would on land. This could be because salt water prevents deterioration of the food.
