1. To create the sugar rim, lightly wet the rim of a wine glass, and dip in a plate of sugar. Then, using a lighter with a handle or a kitchen torch, light the sugar on fire. Be sure to use a glass that can withhold heat. The sugar will melt and caramelize. Turn the glass while the flames burn to ensure even caramelization. Set the glass aside to cool.
2. In a cocktail shaker combine the orange juice, Canton, rum, and hot water. Stir to combine.
3. Strain into prepared glass, garnish with an orange twist, and enjoy immediately while the mixture is still warm.

Makes 1 cocktail.
