Last night I made dinner using a "fireless" cooker. You really do need fire but not for long. A fireless cooker is sort of like using a crockpot only it doesn't need to use electricity all day. It also doesn't give off the wonderful cooking odors, which can be hazardous to your well being in a SHTF situation. You see, food smells travel a very long way. You don't want to be advertising to all those within a 1/2 mile or so that you are making a fantastic meal, do you?
I made a bean stew. I started with dry, rock hard, navy beans. I used two cups of dry beans and boiled them in water. After they boiled for a few minutes I took them off the stove and dumped out that water. I then added more water to the beans and also small pieces of meat, vegetables, and seasonings. No salt. The salt will make the beans tough, so that needs to be added right before you eat. I used enough water to almost fill the pot. I boiled this filled pot for about 15 minutes. I wanted to make sure the meat was hot all the way through. Then I took it off the stove and placed it into my fireless cooker.
What is a fireless cooker? It's a well insulated box that will continue to cook whatever you put into it. If the insulation is good enough your food will be ready in anywhere from 4-8 hours, depending on what you are making. Since I started out with dry beans I knew it would take all day to "cook". People use all kinds of things for their cook box. You can use a cardboard box with insulation and then place another box inside that one. I know someone who has a piece of furniture that is a big storage box. When needed, she converts that into a fireless cooker. Me, I used a cube ice chest.
I have a couple of old bedspreads that are very thin and worn out. I don't need them for blankets. They'd make terrible rags. They'd be perfect for a dog bed or something like that. They make perfect stuffing (insulation) for the fireless cooker. I opened the ice chest and placed one of the bedspreads on the bottom. It came up the sides a bit, which was perfect. I then put in my covered, filled pot. I put the other bedspread on top and down the sides. The two bedspreads plus the pot fit perfectly into the ice chest. I then closed the lid and waited.
