Several reasons why I usually cook in the can. When I started doing this I was usually cooking over a campfire. Leaving it in the can prevents a lot of ash in your meal. There are lots of options for heating a meal in a can, a couple hours under the heater blower of a car or in the hot sun or on a heating
stove is enough. Just make sure your heat source won''t boil water to turn your meal into a food bomb. Also, scraping some of these meals out of the can while they are cold is difficult and degrades the food, raviolli comes to mind, mess around with it when it is cold and you end up with raviolli chunks. When you are done cooking in the can you have the hot water left over that I usually use to rinse out the can so it doesn''t smell up the garbage. If your meal is still in the can and the pot slides off the
stove, the mess isn''t near as bad, and most importantly, you still have your victualls, you don''t go hungry. Nothing really important, to each his own.
