I’ve seen many people complain their food does not remain hot enough till lunchtime. This is because they lack a proper storing sense. Here your objective should be to pack food that does not require reheating at the workplace. Just keep a few things in mind and you can enjoy a warm homemade meal during the break.

  • Before packing a hot meal, pour warm water in the Thermos and keep it for a few minutes. Doing this will ensure the food remains hot for a long while.
  • Also, heat the food in microwave till its piping hot. Or if you’re cooking on the stovetop, make sure it reaches boiling point. Juices or sauce in the food helps to maintain its temperature. Now transfer the piping hot contents in your Thermos food jar and close the lid tightly.
