Po Po Punch

With a vegetable peeler, peel the orange. Reserve the orange and add the peels to a small bowl along with 1/2 cup of the sugar. Cover and let macerate overnight, stirring occasionally.

The next day, stir the juice from the reserved orange into the bowl, discard the peels and whisk to dissolve the sugar. Whisk in the remaining 1/4 cup of sugar until dissolved. Strain the orange cordial into a punch bowl.

Stir in all of the remaining ingredients except the ice and garnishes. Refrigerate until chilled, about 2 hours. Stir the punch, add the big block of ice and ladle the punch into chilled crushed-ice-filled pilsner glasses; top with more crushed ice. Garnish each drink with an orange wheel and a pinch of cinnamon.
