The storm or Kelly kettle Is a great tool for those of us who like to use thermos cooking when we are away from home. You don’t need a huge fire to boil the water that most of the recipes require.

Even though the idea sounds very interesting, I am still very skeptical about the whole thing. I understand that if one is stuck on a desert island without any tools, then the thermos cooking technique would come in handy but in that instance one would have bigger fish to fry, wont they? Also, please guide me some more about the idea of thermos cooking. I mean to ask that how would one got about starting this. I have read the recipes and pretty much understand them but i am struggling to get a start. Please provide some started tips for a complete novice.

The retained heat cooking method has been around a long time and is proven itself to be quite effective whether blankets, straw, sawdust, foam or vacuum insulation is used. The idea is to simply retain and use the heat thats held in the food after it’s been brought to a simmer/boil and let that heat slow cook the food until done. A crock pot simply applies low and constant heat to food in it’s crock to cook the food over a few hours while a thermal cooker retains as much of the heat from the food after it’s been heated on a stove initially to cook the food over a few hours. Any retained heat method whether it’s using a foam or vacuum thermal cooker, thermos vacuum flask, hay box, or wonder box works best when there is sufficient thermal mass in the food being cooked to hold the heat long enough to cook the recipe completely. 2-4 quarts (liters) of food and liquid is generally sufficient to cook most recipes inside a thermal cooker as long as the insulating method is adequate.
A thermos vacuum flask is one of the most efficient means to retain heat so smaller quantities of food can be cooked inside and remain hot enough and long enough to cook it through.
To get started you will need to decide which method of thermal cooking to use and make or purchase the retained heat container to use. For a thermos cooker (or vacuum flask) a wide mouth version with good capacity like the Thermos Nissan 61 ounce vacuum bottle is recommended.
Once you have the “cooker” you can start experimenting with cooking and the recipes such as those found on this blog or on the Thermos Cooking blog
