Can I use ice cream instead of gelato?
Yes, gelato and ice cream are interchangeable in this recipe. Ice cream will create a slightly fluffier float due to higher air content, while gelato offers a denser, creamier texture.
What's the best way to keep the float from getting watered down?
Add the ice cubes before the soda and gelato, and serve immediately. Use chilled glasses to slow melting.
Can I make this ahead?
No—assemble floats just before serving. Pre-mixing causes the soda to go flat and the gelato to melt too quickly.
What other Dr. Pepper pairings work well with gelato?
Chocolate, vanilla, or caramel gelato complement Dr. Pepper's vanilla-cola flavor. Avoid flavors with citrus oils as they can curdle gelato.
