Hot Soup Anyone?
Soup is fantastic food. It can taste like almost anything and can have a ton of ingredients or just a few.

I have some excellent recipes for cozy soups you can try if you need any ideas for excellent soups that will keep you cozy all day.
There’s nothing better than some hot soup on a cold rainy, or snowy day.
If you are working or spending the day in the cold, hot soup will keep your body warm and give you a cozy feel to get you through the frigid temperatures.
Thermoses have been around for a long time. Your parents had one, your grandparents probably had one, and even your great-grandparents most likely had one.
Most people use them for coffee or tea, but they make larger thermoses for foods like soup as well.
Soup thermoses or food jars are just like regular thermoses in the sense that they can keep food and liquids warm or cold.
Food jars are much wider than standard thermoses, and they have big lids that can also be used as bowls. A lot of food jars even come with spoons that are stowed away in the cap.
You can have hot soup all day long with a soup thermos, and they are easy to clean as well.
But like most things, not all soup jars are made equally. I’ve made a list of the best soup thermoses out there for any style or need.
No matter which you buy, your soup will be safe and warm for hours.

The cover lid is made with silicone with a carry handle attached to it and also doubles as a bowl.
The cap has a foldable spoon that has its own compartment. Under the spoon, there is a pressure release button that is unique to this food jar.

Frequently Asked Questions About Soup Thermoses
How do I make my thermos or food jar stay warm or cold longer?
Any vacuum insulated thermos or food jar needs to be prepped to get the best performance.
If you need the thermos to stay hot, prep it by pouring boiling or hot water into the jar and leave it for around 5 minutes.
This will heat the insulated area, making ready to stay hot for longer. It also won’t cool down your food when you pour it into the jar.
If you want your thermos to stay cool, prep it by pouring cold water into the jar and leave it for at least 5 minutes, or you can leave it in the fridge overnight with the lid off.
This will make the insulated area cold and keep your food or liquids cold for longer.
Can I put milk or dairy products in my thermos or food jar?
Yes, you can, but dairy products can grow bacteria faster than other types of foods.
You shouldn’t leave dairy products in a food jar or thermos for as long as you would other foods.
The FDA recommends not leaving dairy products out for more than two hours and one hour if the air temperature is above 90 degrees F.
For more information, you can read this article by the FDA on storing food safely.
A thermos or food jar will give you a few more hours of safe food temperatures for dairy products and milk.
The end decision is up to you, but I wouldn’t recommend keeping cold dairy products or milk in a thermos or food jar for longer than 4 hours.
Will a thermos or food jar keep ice cream frozen?
If adequately prepped, a good thermos or food jar should have no problem keeping ice cream frozen for a few hours.
I would recommend prepping the thermos by keeping it in the freezer for a few hours with the lid off.
No thermos or food jar is made equally, so do a few tests with your own thermos to see how long it will keep ice cream frozen.
Will a thermos or food jar keep ice frozen?
Much like ice cream, thermoses and food jars can keep ice frozen for a few hours if appropriately prepped.
Prep the jar by putting it in the freezer for a few hours with the lid off.
You should be able to keep ice frozen for at least a few hours after this.
Will a thermos or food jar keep solid foods like mac and cheese, chicken nuggets, and pasta warm?
The short answer is yes. Foods with a sauce like mac and cheese and pasta will stay hot longer than foods like chicken nuggets because they fill up the space in the food jar better.
For any food that needs to be kept warm, it is essential to prep the thermos or food jar by putting boiling water in it for at least 5 minutes.
Chicken nuggets are a little tricky because bacteria can grow so fast if you want to put them in a thermos, I recommend eating them within a few hours.
A tip to keep them from getting soggy is to put a paper towel under the nuggets to absorb some of the liquid that will collect from the steam.
Who invented the thermos or food jar, and when?
The very first vacuum insulated thermos was invented by a Scottish scientist names Sir James Dewar in 1892.
The first thermoses were made of glass. William Stanley Jr. invented the steel vacuum insulated thermos that is so popular today in 1913.
Can a thermos or food jar be washed in the dishwasher?
Most of the time, the answer is no.
A stainless steel thermos or food jar will rarely be dishwasher safe, and if it ever is, it is recommended to put it on the top rack of the dishwasher.
When it comes to stainless steel, it’s always better safe than sorry.
Most companies will always recommend washing their products by hand.
How do I clean my stainless steel thermos or food jar?
You should never use abrasive materials to clean a stainless steel thermos or food jar.
Things like scrubbers and steel wool will scratch and dull the steel. To clean a thermos or food jar put a little soap in the jar and fill it will warm water.
Let it sit for around five minutes. Wash with a soft rag or sponge. Then dry with a towel.
For a deep clean, put one part baking soda and one part warm water in the jar and let sit for an hour. Then wash out with soapy water and a sponge or rag.
Are thermoses or food jars recyclable?
Stainless steel is a recyclable material.
Usually, large stainless steel products like thermoses and food jars need to be taken to a scrap metal recycling company.
You will even receive a little money for bringing in your stainless steel product.
Can thermoses or food jars be put in the microwave?
If you have a stainless steel thermos or food jar, it cannot be put in the microwave.
Metal of any kind should never be placed in a microwave.
Can I put a thermos or food jar in the freezer?
