Step 1

Bring the water and milk to a boil in a heavy-duty sauce pan or small Dutch oven. Stir in the salt.

Step 2

Gradually sprinkle the polenta into the pan while whisking at the same time. Turn the heat to a very low simmer, cover and continue to cook the polenta for 25-35 minutes, until it's thick, fluffy and begins to pull away from the sides of the pan. Stir frequently so it doesn’t stick to the bottom of the pan.

Step 3

When it's done, remove from the heat and stir in the butter, cheese and additional salt to taste if needed.

Step 4

Serve warm, sprinkled with rosemary and additional cheese, if desired.
