Thermal Cooking

What is thermal cooking? Well it’s like a slow cooker, but it does not use electricity at all. The short and sweet of it is that food is heated to boiling for a period of time 5, 10, 15 minutes and then put into an insulated structure. The covered pot will retain all the heat and the food will slowly continue cooking for several hours.This cooking concept is not new. While doing some research I found a newspaper article from the late 1890’s describing the same method. I also found a drawing in the book Experiment Station Work, XLI from 1907. If interested in reading the article it can be found over on the Internet Archive.

Well my cooker is not made from wood but the concept is the same. I was able to duplicate the method using a lidded pot and a cooler. Considering the cooler took up so much counter space and the hot pot warped the plastic on the inside of the cooler I finally decided to purchase a small crockpot sized thermal cooker.

It’s very simple to use and there is no worry from leaving an electric appliance plugged in all day.

The past few days I’ve tried a couple of soup recipes and can say that I’m really pleased with how they turned out.

The first recipe I tried was my own take on a chunky chicken soup. It’s more like chicken and dumplings, but without the dumplings.

Then again then last night I did a venison vegetable soup.

The fun part is that once these soup mixes get heated up and placed into the cooker there is nothing left to do. After 4-6 hours dinner is ready! On the plus side I have plenty of soup that will end up in the freezer since I made so much!  I put 4 quarts in the freezer for later this year!

Remember that this method takes time to cook, so start early!

  1. Nice recipes! The cooker sounds great, I love experimenting with other methods! We tried a few in Girl Scouts, solar box, dutch oven, card board box oven – fun stuff! This also looks as if it would be perfect for taking a hot dish to share at a pot luck instead of dragging along a crock pot – what do you think?
