In a medium saucepan, pour in 2 cups of Orange Crush soda and heat over medium flame. Stir occasionally for about 10-15 minutes until the soda reduces and thickens slightly into a syrupy consistency. Remove from heat and let cool to room temperature.

In a large mixing bowl, combine the cooled, reduced Orange Crush soda with 1 cup of heavy cream and 1 cup of sweetened condensed milk. Whisk until all ingredients are well-blended and achieve a smooth, creamy texture.

Transfer the mixture into an airtight container and place it in the freezer for at least 4 hours or until completely set.

Scoop the sherbet into chilled bowls or sugar cones and drizzle with a splash of cold Orange Crush soda for a fizzy finish.
