Q1: What exactly makes a Dr Pepper "dirty" at Sonic?
A1: A dirty Dr Pepper incorporates traditional fountain soda mixed with added flavor syrups (such as coconut, vanilla, or banana), fruit purées or juices, and dairy elements like sweet cream or coconut cream.
Q2: Does the dairy curdle in the acidic soda?
A2: Yes, separation can happen quickly. Phosphoric and citric acids in the soda naturally curdle dairy cream if the drink sits too long or warms up. It should be consumed immediately while thoroughly chilled over ice.
Q3: Can I customize any drink at Sonic to make it a dirty soda?
A3: Yes. You can use the Sonic app or order at the stall to add sweet cream, coconut cream, and any available fruit syrup to any base fountain drink on the menu, including colas, root beers, and lemonades.
