Samuel J TanKitchen & Cooking 0

There are few things as heartwarming as a mug or in this case, a jar of tasty, warm, perfectly seasoned, creamy, filling soup on a cold wintery day. These food jars, ranging from a small 10 ounces to a relatively large 25 ounce lunch jar, all provide the ability to keep food warm for several hours – which make them perfect for a healthy warm soup lunch packed from home, ready for lunch-time at school or in the office.

Most of these thermoses are single containers that will keep food warm for a good 4 to 5 hours or longer. A number of them are also beautifully patterned and decorated to appeal to school-age children, and of course, for more options, the larger bento-styled thermoses offer multiple bowls within the carrier – so even a complete meal is possible!

Whether you decide to fill your food jar with a thick creamy soup, or a clear bone broth topped up with sliced and shredded vegetables and noodles, a warm meal is simply something to look forward to in the colder months and in the heat of summer, keeping food cold is also a possibility!

Here in this post, we have, for convenience broken down the food jars by size. The large bento-styled thermoses are listed with the large jars. Do you have any favourite food jar recipes?
