May I suggest the dreampot It is sold from Queensland they come in 3 different sizes 3 ltr,5 ltr and 6 ltr. They are not cheap but work extremely well. I have the 3 ltr and the 6ltr. and i am very happy with them. Basically they are passive cookers. You can take them to the beach on a boat anywhere. They cook whilst you travel or keep cold as well. Look it up on the net you will get all the info. Frans.
Pumpkin Pie, what is this Indian Pot you tested? Do you have a link? I am very interested.
The Thermoserver would be much better if it had a SS lid, IMO.
Trudy introduced me to an Indian shop in Adelaide a while back so today when I went on a trip with my carers' group to the Central Market, I went to the shop and bought myself a food warmer. It is the Milton brand like PP bought and although it has 1500 on the bottom, it only holds 1 litre which is what I wanted as I have a Thermoserver for bigger quantities. I bought it from Indian Spices, 14 Market Street, Adelaide and also stocked up with my spices whilst there. There is another Indian shop opposite this one so it may be interesting to compare stocks, I only went into this one today. Price $20 and I love the lockable lid feature.
