So I read the instructions and it says "add the liquid" No reference to whether it is to be hot or cold.
On the occassions I have added hot water soup has been... well - s(o)uper!
I added cold water after reading the instructions again and something online which referred to using only cold water.
Twice I've used with cold water and lentils have stuck.
Just read this on the Morphy Richards website:
It’s always best, and most efficient, to boil the water used for the stock or liquid addition just before adding it to the soup-maker. If you use water straight from the tap, you may find some vegetables aren’t quite cooked when the soup’s ready, especially if the vegetables are cumbersome or tough. Starting with hot stock gives it a better chance to add more flavour and taste.
So... hot or cold????
