Top Tips for Using Insulated Food Jars

There isn’t much that can warm you up on a cold day quite like a hot meal, and you can have a warm meal all packed and ready to go with you with your insulated food jar. Work, school, or even your picnic can be a warmer place with the use of these handy jars that keep your food hot for as long as five hours. Every bite will still be just as warm as when you packed it.

From the spicy vegetable curry to the thick soup, the choices are nearly endless. But there are just one or two things to get right in order that you can get the best out of your insulated food jar. Here are some tips to ensure that you get the most out of these amazing jars, so that your food can be kept warm, fresh, and delicious.

Selecting the Right Insulated Food Jar

Size and Material Considerations

I always ensure that I am checking the material and the size when I am selecting an insulated food jar. The smaller jars, which are generally 300-500ml, are perfect for snack time or for a small meal. 

The larger, 600-1000ml, are good for soups and stews. I will always opt for stainless steel because this selection is tough, rust-resistant, and is very good for insulation. Plastic jars are lighter, but they do not insulate as well. Glass jars are just as good, but heavier and are breakable, so they tend to be less preferred for use on the go.

Features to Look Out For

There are many other aspects that make an insulated food jar efficient and convenient. When buying, I always make a point of looking out for double-wall vacuum insulation that gives hours of temperature lock.

A wide-mouth construction makes it easy to fill in and eat and further easier to clean. Leak-resistant lids are, of course, an absolute must if the jar is to be used for any liquid dish, to prevent it from spilling. Some jars come with a little more than carrying food, like attached utensils or other separate compartment aspects to keep some food items apart. A jar with an exterior that is easy to grip makes for a better choice as it assists in avoiding slips when you are on the move. 

Here are some top options that are great for kids:

Get Your Insulated Food Jar Ready

Pre-Warming or Pre-Cooling Techniques

Preheating an insulated food jar will help it perform optimally at keeping your food warm. Begin by filling the jar with boiling water. Let it stand for about ten minutes, and then pour it out and immediately pack your hot food. This conditions the jar to keep hot temperatures longer.

Pre-cooling is also best for cold items. Fill the jar with cold water and let it remain for about ten minutes. Pour off the cold water and add the cold food right away. This step maximises the jar’s tendency to retain the temperature of the contents.

How to Clean and Maintain Your Insulated Food Jar

To best maintain your insulated food jar, it should be washed after every use. 

  • Fill the jar with warm water and add a small amount of washing detergent. Soak the jar for three to five minutes to assist in loosening any food particles. 
  • Lightly scrub the inside of the jar on all surfaces with a bottle scrubber wrapped in a dishcloth, get in the hard-to-reach pockets in particular. 
  • Thoroughly rinse the jar with warm water and towel dry to eliminate any excess moisture.

Do not submerge your entire jar in water to avoid damage to the insulation.

Eliminating Stains and Odours

Stubborn odours and smells can be a little pesky, but there is a way to combat them properly. 

  • Combine baking soda and dish soap, and work the mixture into a microfiber cloth. 
  • Gently clean the areas that have been marred with stains, working in the direction of the grain of the metal if possible. 
  • Rinse with warm water, and then pat with a towel to dry it. For more problematic stains or smells, place the jar in some soapy water and let it soak for a couple of hours and then scrub and rinse. 

This will enable any residual scents to be absorbed and ensure that the cleanliness of the jar is complete. Proper maintenance of your insulated food jar will not only ensure its durability, but it will also continue to keep your food fresh and delicious.
