Cooking With a Thermos
How to cook with a thermos
In this article we will cover an efficient and simple way to cook most things that require boiling water.
I prefer thermos cooking to normal pot and water boiling methods because I do not have to constantly stir the pot, I cannot burn the ingredients to the pot, I can multitask with meal preparation without taking up a spot on the stove, and I can prepare something the night before or before a long trip that will be warm.
- Tea kettle or other way to boil water
- Grain, pasta, vegetables, meat, or whatever recipe ingredients are to be cooked.
Look up the recipe to be cooked. I would start with googling something “normal” and then add “cooking with a thermos “.
- Pasta, oatmeal, or quinoa is a good starting point.
Pour water (hopefully filtered) into the kettle and start heating.
- I find measuring cold water easier than measuring boiling water so I measure into the tea kettle rather than measuring into the thermos.
Add the ingredients into the thermos as the water is heating.
- If what is being cooked will expand ensure room is left in the thermos for expansion.
- Measure what is put into the thermos and measure how much water is added.
Once the water is boiling, add the determined amount into the thermos.
Start the timer on the stove or watch the clock.
Put the cover on the thermos and shake vigorously.
Place the thermos on its side so the contents do not pack to the bottom.
- If bored shake the thermos a few times throughout the cooking to keep things from sticking together such as highly processed pasta.
Once the timer is done, open the thermos and check the contents for thorough cooking.
- If the contents are not cooked thoroughly put the cover on and let sit longer.
- If the contents are cooked to properly pour off excess water, if necessary, and serve.
Mark the time for thorough cooking along with the amount of contents cooked and the amount of water for future reference.
- Keep records of the cooking times for different ingredients.
- The first time something is tried it will not be perfect so records will help for next time.
- Large mouth thermoses work better for cleaning and large pasta.
- Kraft Mac and cheese turns to mush and sticks together if over done and leads to a cleaning nightmare.
- A long wooden spoon helps to get the contents out of the thermos.
- Pouring the water out of the thermos is simple by barely loosening the cap to let water through like pouring coffee.
- Many people recommend preheating the thermos with boiling water but I have found it does not make that much of a difference and takes more time and hot water.
- I find it easier to add the measured amounts of cold water into the tea kettle. This way I don’t have to try and measure cups of boiling water and can just pout the entire contents into the thermos.
- Thermoses will lose their “thermos” properties when the vacuum is lost between the inner and outer layer.
- I bought many thermoses at the thrift store and they work like new.
- I did buy some that did not hold their temperature well.
- I get my thermoses for pennies on the dollar so even with a dud every now and then I am still ahead from buying new.
- To tell if a thermos is working fill two thermoses, one that works and one that is being tested, with the same amount of water and check them every hour with a thermometer. If one drops in temperature drastically while the other holds a high temperature one is faulty. I dispose of the faulty thermoses so no one will have to deal with cold ingredients again.
