How to Cook Food in a Thermos

• Organic Prepper - Daisy Luther

Looking for a way to cook food off-grid but don't have a fireplace or indoor method to do so? I have fantastic news. That thermos you have stashed away is good for far more than keeping your coffee hot in a cold house or making homemade yogurt (seriously – yogurt!) If you have a way to boil water and a thermos, you can make all sorts of food.

This is a method made popular by boaters because it uses far less fuel than cooking on a stovetop and reduces the potential for a fire on board. But, it's the perfect method for land-loving preppers, too. If you have limited fuel or lack an elaborate off-grid cooking set-up, the humble thermos just might be your new best friend. And in these times of outrageous energy bills, having a cooking method that relies on less power is always a good idea.

Here's everything you need to know about how to cook food in a thermos.

What kind of thermos should you use for cooking?

You can't just pick up a cheap knock-off in the back-to-school aisle and expect to make meals in it. Those are fine for keeping a meal warm until time to eat, but they cannot handle the boiling water necessary for cooking, nor do they hold enough heat.

While I'm not generally a brand-name shopper, there's a reason that the Thermos brand has become the ubiquitous name for vacuum bottles. The quality is very high, and you need that kind of excellence for a cooking method on which you plan to depend.

Look for a bottle made from stainless steel. No plastic liners, no glass liners – just steel. I prefer a wide-mouth bottle because it's way easier to fill and clean, but if you are getting a big bottle, you'll have to go with a narrow mouth. I use my canning funnel for filling it and a long skinny spatula for getting my food out. A long bottle brush will make clean-up far easier. All of these accessories have many different uses and are widely employed in my kitchen.
