Rather than making food from scratch, or buying an extortionate butty at an event she was attending, Muddy Madam decided she wanted to take a bowl of her home made soup, but the only food flask we had was tall and a bit narrow - great for one of my chillis, but not for soup, so she went on the hunt for a new one. It didn’t take her long, as already a huge fan of Klean Kanteen’s products it was the first place she looked and she ordered their mid-size 16oz (473ml) insulated TK Canister.

Made from durable stainless steel, it is easy to clean, stackable and dishwasher safe. With an internal thread design for increased thermal performance and a newly designed bowl-shaped base, it’s wide enough for scooping soup. The lid locks in leakproof storage in just a quick quarter turn and features an easy-carry swivel loop.

Klean Kanteen’s Climate Lock double-wall vacuum insulation keeps contents hot for 7 hours and cold for 25 hours.  At 8am, to test this, I filled it with boiling water, then at 8.15am, after emptying the water I filled it with a homemade chilli with rice. Poking a cooking thermometer through to the centre it read 77.4°C. I then sprinkled a bit of cheese on top (which did come straight from the fridge so would have dropped the temp. a smidge), and popped on the lid.  At 12.15pm it was dinner time (lunch if you’re a southerner), and after probing my chilli again, the temperature was still a toasty 61°C.

Unless you enjoy the sound of nails scraping on a chalkboard don’t use metal cutlery (I won’t make that mistake again).  Instead dig out your bamboo spoon or plastic spork, as even now, a few month’s after I first used it, I still get a shiver down my spine at the sound it made!

Overall the TK Food Flask has been a wonderful addition to both our outdoor kitchen and work dinners for soups, stews and chilli - just heed my warning on the cutlery!
