A food flask is a perfect partner to ensure you always eat like a king and have healthy nutritious food ready to go. A good food flask will be great for helping out with any new years resolutions and saving money by not buying lunches out and about.

Food Flasks are great for travel, perfect for lunch boxes and ideal for a day out at any time of the year. You can have hot dogs and ice cream without the price tag. Or a healthy meal where you know exactly what the ingredients were. Plus there's nothing better on a cold winters day than knowing you can have a steaming bowl of stew without even having to leave the office.

Insulated food flasks

A vacuum insulated food flask will keep soups and stews hot for hours. You can take a bowl of hot porridge to work with you to eat at your desk or have a nourishing and warming soup when out on a long walk. Food flasks can also be used for warm salads, pasta or rice dishes, curries or chillies. Pretty much whatever hot food you fancy.

Combine with a slow cooker and you can cook your meal overnight and transfer it piping hot to your stainless steel food flask in the morning. Meaning you’ll have a nice hot lunch with minimal fuss. Just take a spoon or fork (or a bamboo spork) with you and eat straight from the wide mouth of the container. A complete dining solution.

Insulated food flasks are also great for cold food or drinks. They’re perfect for keeping salads chilled until lunchtime if you don’t have access to a fridge, ideal for school lunches on hot days, and can even be used for carrying ice cream on a picnic or a trip to the park. Meaning a food flask is well worth the price you pay and will end up saving you money in no time.

The vacuum insulation means the outside of the flask will stay condensation free and cool to the touch regardless of how hot or cold the contents are. And the durable stainless steel construction makes them perfect for throwing in your bag without worrying about leaks or breakages.

Tips for keeping food hot

If you want to fill your flask in the morning and enjoy a nice hot meal at lunchtime, here are a few tips for making sure you don’t end up with a lukewarm lunch:

  • Pre-heat the flask with boiling water. This will stop your food instantly cooling down when it hits the sides of the flask.
  • Heat your food hotter than you would normally eat it. However great a thermos is at retaining heat you’ll still lose some over time so if you know you won’t be eating for a while making the food extra hot allows it to cool a little and still be the perfect temperature to eat.
  • Fill it up. If there’s a large amount of air at the top of the flask your food or drink will cool more quickly so choose a flask that’s the right size for you.
  • Once you’ve closed the lid don’t open it again until you are ready to eat.

Tips for keeping food cold

  • Pretty much the same as above but chill your flask in the freezer (without the lid on) or fill with iced water and leave for a minute to chill the inside of the flask.
  • Fill to the top to minimise temperature transfer with the air.
  • Make sure the food goes in cold.
  • And don’t keep opening the container if you can help it.
