I became interested in this pot as I think it is an energy saving device.
Standard cooking over stoves and fires, done for centuries actually means loss of heat and hence energy to the surrounding by way of convection, evaporation and conduction. Most of the heat I think is lost through evaporation. Not only is heat lost but also valuable moisture.
The thermal pot is basically something like the old thermos flask but this time it is a pot. What it does is that if there is enough heat put into the pot by cooking, and the pot along with all its contents are put into a thermal system then the heat is contained along with the moisture. The contained heat continues to cook the contents of the pot and at the same time keep the moisture in.
Understanding this principle, then one has to regulate cooking in terms of how much heat is in the system and how long the food remains in the pot.the other advantage is that the food remains warm hence has the benefit of
a) having warm or hot soups at any time without having to reheat hence using more energy
b) great for outings where a nice hot bowl of soup will be great as it travels down the oesophagus and hits the spot in the stomach... ahhh
The pple that made it, I understand it was originally Zojiroshi then now of course there are many brands that make it too. In my last trip to Japan I found some made by thermos and it is a fraction of the cost of the Zojiroshi brand.

Oh now I understand..
I saw a thermal pot on the front page of Today and it was $88. What do you think?
And does food become basi (ie. spoil not in case u've forgotten ur malay but for non malay readers) in it if u leave it too long? I'm just thinking, if I cook with it during Ramadan at night then I can have a hot meal in the morning without much fuss rite?
Basi... hmm wait let me check my malay english dictionary first.... oh yes, now i get it, to go bad, stale or rotten... depends of course what is in it and if tahu etc i dont know, so far it is ok with me. it remains warm so i think it does not get basi that way. If for ramadhan then for 12 hours... hmm i dont know if it will keep hot but I think definitely warm. I think you can get cheaper ones at seng siong, unless you are too atas to go there... ha ha.. anyway $88 is about right
Hmm.. Let me check my Malay dictionary for the meaning of "atas" oh yes, to be pompous and feel thyself above the commoners.
Happy is so sold on the idea of the thermal pot just because you have it! I am still considering. If I find someone with the UOB card, its only 40 bucks!
eh what happened, this blog is so abandoned!
