Juice the oranges. You should drink 360 ml, or approximately 112 cups, of juice.

To a pitcher, add the ice. The evaporated milk, sugar, and vanilla should be added to the ice and thoroughly mixed.

When everything is incorporated and just beginning to foam, add the orange juice.

Distribute equally across 4 glasses.

Serve each glass immediately after adding an orange wheel as a garnish.

Enjoy!
