4 cups water, plus more as needed
4 cups milk, plus more as needed
3 tablespoons butter
2 teaspoons salt
2 cups polenta
1/2 cup creme fraiche
1/3 cup Parmigiano-Reggiano
In a large saucepan, bring the water, milk and butter to a boil. Add 2 teaspoons of salt to the water and whisk in the polenta. Whisk constantly for 3 to 4 minutes to prevent lumps. Simmer for 45 minutes, partially covered and stirring every 10 minutes, until the polenta is thick, smooth, and creamy. Add the creme fraiche and Parmesan.
