Thermos cooking has been around since they were first introduced but if you aren’t familiar with the concept and if you haven’t tried it out then keep on reading and check the video below.
Thermos cooking is one of those great survival tips. Its simple, it can be done with common objects like a thermos found in most households, its probably the most fuel efficient way of cooking and it addresses a key survival problem: Preparing food when the grid is down. We learned about making a simple can stove with the Supercat stove video. Still, boiling water and cooking food are two different things. Cooking requires more time and (more important) more fuel. Well, you don’t need to worry about that with thermos cooking.
Simply preheat the thermos with a bit of boiling water, remove it, introduce the food (think rice, pasta, lentils) and fill it up with four parts of water for each part of food. Tighten the cap, shake a bit and that’s it. Let it sit for some time. For rice and lentils it can be 8 to 10 hours. For pasta 15-20 minutes will probably do. You’ll need to experiment to see how much water you exactly need for each food and how long it takes to hydrate and cook properly. A good Thermos makes a difference. The ones I used were rated for 12 hours and after 12 hours the water inside was still too hot to touch.
Here’s the video experimenting with rice and lentil Thermos cooking.
Here’s one of the best selling Thermos in Amazon in case you need to grab one for your kit.
