I have tried a few different soup pots and ALL the ones I have tried burn whatever is at the bottom of the pot unless you stir constantly.
MIL has old pots for soup/stewing that she got from her mum and they have the heavy, black base so she just chops everything up, adds the stock and leaves it to boil on the hob for an hour and nothing sticks burning at the base of the pot! Of course, you don't get these any more.
Oh and it has to be relatively inexpensive...
TIA :)
