For a more intense citrus flavor, add the zest of one lime and one lemon to the punch bowl. To make an alcoholic version, add 1-2 cups of tequila to the punch bowl before adding the ice. Adjust to taste. If you don't have white cranberry juice, regular cranberry juice can be used, but it will change the color and flavor profile slightly. Garnish with fresh mint sprigs or lime wedges for an extra touch of sophistication.
