Let’s not overlook the fuel consumption benefit. It takes about 3 minutes to boil a cup of water on my Pocket Rocket stove. When the water reaches the boiling point, you pour it in the bag to finish cooking. If you cook your meal in the pot, you have to bring it to a boil and let it simmer on the stove for another 7 to 10 minutes, which, in turn, consumes more fuel. Usinig more fuel means carrying more fuel, which of course means more weight.
