Combine the orange soda and sweetened condensed milk in a large bowl.
Whisk until milk is well incorporated.
Using an Ice Cream Maker
If you’re using an ice cream maker, pour mixture into it immediately after whisking and begin the churning process. If you are wondering, the air bubbles in the soda dissipate during the churning and the liquid will condense.
Churn for about 1 hour. When it is partially frozen, transfer the mixture to a bread pan and freeze 6-8 hours, or until solid.
Preparing by Hand
If you are not using an ice cream maker, after whisking very well, transfer the mixture to a bread pan and freeze.
After 1 hour, stir the mixture and then place back in freezer.
Repeat this process every 2 hours, stirring at least twice during the freezing process.
