Maple Negroni

This feels like a perfect fall cocktail. Slightly sweet but also retains the crisp flavor of Compari. Maple replaces the standard simple syrup and creates a much deeper flavor.
1 ounce maple syrup
1 ounce gin
1 ounce Compari
1 ounce sweet vermouth
½ orange wheel
Add all ingredients except the orange to a cocktail shaker. Shake with ice and serve with one large cube and the orange.
