Want to know how much heat it holds ? Here's an example.
Here's an example, I cooked soup in the Bunyip's Thermopot then put it in the EasyOven, 6 hours later it was almost too hot to eat !! But that's not all, I put the soup back in the Bunyip's Thermopot and back in the EasyOven thermal bag and forgot about it...then next day at about 10am the soup was still warm ! Not steaming hot but still warm and this was in the middle of winter !
