* Put all the ingredients in a large bowl and stir them.
* Place the mixture in a non-stick pan over a moderate heat and keep stirring. The mixture will look very lumpy, but don't worry - as it comes to boiling point, it will begin to resemble dough.
* When the mixture forms a ball, remove the pan from the heat and allow it to cool for a while.
* Knead the dough until smooth.
(This dough can also be made in a microwave.)
