One of the most useful "cookers" I have in my kitchen is a Thermal Cooker. All you have to do is put all the ingredients in the pot, take it to a boil, then leave it to cook some more for a few hours (no electricity required during this phase). And the food from the pot is nicely warm when you are ready to eat.
What is a thermal cooker and how does it work? A thermal cooker (also called a thermal cooking pot) works much like a crock pot. It is made up of two pots:
•Insulated outer pot
•Stainless Steel inner pot
The food is put to the boil on the stove in the inner pot before being placed in the outer pot. The heat (from the boiling process) is retained inside the pot, allowing the food to continue cooking slowly.
The cooker is excellent for soups and stews, anything you would normally use a slow cooker or crock pot for.
The thermal cooker can also retain cold temperatures, and can thus function as an ice-box or wine cooler.... Read more.
