What is thermos cooking and what is a thermal cooker?

Thermal Cookers are a wonderful way to slow cook your meals to get great tasting food with very little energy consumed. In an emergency and when fuel for cooking is scarce (and even when it's not), using a thermal cooker can save over 80% even 90% of the fuel consumed for cooking a meal compared to a propane, wood or other fuel source. Thermal cooking is a simple process much like a crock pot or slow cooker but without the electricity. Simply place the ingredients of your recipe inside the stainless steel inner pot and on your cook stove, and then bring the contents to a simmer. Depending on the food, leave it on a simmer for a minute at the shortest to about 25 minutes at the longest to fully saturate the food with heat. Once saturated, remove the pot from the stove and quickly place it inside the thermal cooker outer pot and close the lid. The thermo pot keeps the heat inside and the food slow cooks in it's own heat until done.

Thermos cooking is using the retained heat built up in food as it's simmered on the stove as the means to slow cook the food while it's kept inside a thermos or vacuum or other insulated container such as a thermos pot, bottle, flask or other thermal cookware.

Inside a thermal cooker

A thermal cooker is a very simple and easy to use appliance designed to hold a cook pot inside an insulated thermal container. The best performing thermal cookers are made of a steel vacuum insulated outer pot with a heavy stainless steel inner pot and lid. They are basically a non-electric slow cooker or crock pot which describes them quite adequately in simple terms.

How a thermal cooker works

To use, simply add the ingredients of your recipe into the stainless steel inner pot and place it on the stove. You bring the contents up to a boil and depending on what it is you are cooking, leave it simmering for a few minutes to about 30 minutes before you turn the stove off and place the inner pot into the insulated outer pot and close the lid. The remaining cook time takes place within the cooker with the heat retained in the boiling hot food inside the thermal cooker finishing the job. That's it, simple and easy to use. You can prepare a whole days worth of meals in the morning and by lunch time the food will be ready to eat. A dinner meal will also be cooked and ready because the insulated thermal cookers can keep hot things hot for 6-12 hours depending on the food and how much is being cooked. Thermal cooking is a great option for traveling on the road in an RV, boondocking or even camping that provides a window of meal preparation time in the morning but where the food doesn't need to be ready to eat for hours later.

For the best quality thermal cooker choose the THERMOS brand models as they are the best constructed and highest performance thermal cookers made. For a good quality thermal cooker and on a price performance basis the Saratoga Jacks thermal cookers are hard to beat. Both Saratoga Jacks models feature two stainless steel inner pots which lets you cook two things at once. If you've purchased any type of freeze dried or dehydrated food storage, using a thermal cooker to heat and cook it is the best solution available in our humble opinion!

Once brought to a boil and simmered, remove from stove and place in outer thermal hot pot. Thermal technology creates a convection effect by using the steam produced inside to circulate and continue cooking for up to 30 minutes and warms for up to 8 hours. Food is cooked in its own moisture and steam, so nutrients and foods healthfulness is preserved. Compared to a pressure cooker, thermal cooking can be up to 30% more energy efficient and can be left unattended once taken off the stove.
