What is a Wonder Box? A Wonder Box is a heat retention cooker. The major benefit of the Wonder Box is to reduce the amount fuel you need to cook meals. A source of information I read, stated that you can save up to 80% of your needed fuel by using a Wonder Box, because the heat used for simmering is eliminated. What kind of meals can you cook in the Wonder Box? Any meals that you can cook in a Crock Pot. You have to allow a little more time.
A Wonder Box is two cushions placed in a 20 gallon container with a lid. There is a top and a bottom cushion, filled with bean bag filler. You can use also shredded foam, shipping popcorn or wood chips. With wood chips you will have to empty the cushion before washing. (I ordered bean bag filler on-line from Wal Mart), (and I also bought a container at Target for $8.00 on sale) The top cushion takes 7 gallons of beads and the bottom takes 12 gallons, according to directions. (I filled mine with a less and it works well.)
I used a piece of flannel to make mine. It had frogs on it and I love frogs. (Good eating too). They recommend a soft cotton or broadcloth material. Cotton works best as it will not melt when touching the hot surface of the pot. (You can use a piece of foil on the bottom also, between material and hot pot.)
What is great about the Wonder Box, it can also be used to keep things warm, I’ve tried it when taking a cooked meal to my mother in laws and I needed pot holders to take the dishes out.
