Thanks for bumping this and therefore making us aware of other options for Thermoservers. I know tupperware have/had one too. Not sure how effective it is. The Ikeas one seems cheap though and it would be good if someone could test the temperatures of these for us.
The one that I purchased at the Indian kitchen store in Toronto, Ontario was called "Kitchen Sense stainless steel hot pot". It is from the Ashridge Trading Company--www.ashridgetrading.com--am just trying it to-day, although the store clerk told me that they do work for keeping things hot, they were not to be used for cooking.
