Start to prepare the rigatoni according to the manufacturer's instructions. While the pasta boils,
heat the butter in another cook pot, and add the flour when the butter sizzles.
Blend the cream cheese in the butter/flour mixture with a spoon until creamy.
In an incremental fashion, add a bit of water, blend, a bit more water, blend, etc,
keeping the mixture smooth with stirring. Add the blue cheese and condiments.
Add the cooked rigatoni to the sauce pan, and boil until the sauce coats the pasta without being runny.
Lovely with a glass of white wine, if you can!
