Creamy Polenta

In a medium pot over high heat, bring 9 cups water and salt to a rolling boil. Whisk in cornmeal and continue to whisk until water begins to boil again. Decrease heat to low; continue to cook, stirring every 5 minutes, for 1 hour.

Remove from heat and whisk in cream, Parmesan, and butter. Let stand 10 minutes before serving.
