Combine all ingredients, except blueberries, in a saucepan.
Bring to boil.
Then reduce heat to a low simmer.
Cook for 20-25 minutes partially covered, stirring every so often.
The mixture should become creamy, although it will remain a little chewy.
In the last 5 minutes of cooking, add most of the blueberries and stir through.
Add additional water if the mixture becomes too thick.
