Congee is a delicious thick Chinese rice soup.
Wash the rice in several changes of cold water.
In a pot, at room temperature, soak the rice overnight in the cold water with plenty of salt & a dash of vegetable oil.
The next day, add the 1 litre of fresh water & over high heat, bring to the boil.
Reduce the heat to a low simmer, cover & cook for 2 hours, stirring from time to time until the congee is almost smooth & very creamy.
