Use this recipe when making our Polenta Wedges with Asparagus and Mushrooms.
In a 4-quart pot, bring milk and broth to a boil over medium-high. Gradually whisk in polenta. Continue to whisk until polenta thickens. Reduce heat to low, season with salt and pepper, and simmer gently, stirring occasionally to prevent sticking, until cooked, about 25 minutes.
Pour 4 cups polenta into a lightly oiled 8-inch square baking dish; cover with plastic wrap and refrigerate for the next day or two.
To create neat wedges, loosen and invert polenta from the baking dish, then cut into pieces.
