Polenta with Corn and Thyme

In a large saucepan, melt 1 tablespoon butter over medium-high. Add corn and thyme. Cook, stirring occasionally, until corn is warmed through, about 1 minute. Add milk and water and bring to a boil. Slowly whisk in cornmeal. Cook, stirring constantly, until mixture is thick and creamy, about 6 minutes. Remove from heat and stir in remaining 1 tablespoon butter and Parmesan. Season with salt and pepper; serve immediately.
