In addition to the syrup and cinnamon, you can add just about any topping here: dried fruit, banana, nuts, cream, fruit butter. Consider the polenta a blank canvas and have fun.
3 cups milk, plus more for serving
1 cup quick-cook or instant polenta (look for it in the International aisle of the market)
3 tablespoons maple syrup, plus more for serving
1/2 teaspoon kosher salt
In a medium saucepan over medium-high heat, bring milk just to the simmering point. Add polenta in a thin stream, whisking constantly. Add maple syrup and salt and continue to whisk until polenta thickens noticeably, 1 to 3 minutes. Serve with maple syrup, a little milk, and a dash of cinnamon.
