Pro Tips
• for the Perfect Slushy

• Pre-chilling your blender pitcher and glasses in the freezer for 15 minutes helps keep the slushy frozen longer.
• Experiment with other sugar-free sodas like Diet Dr. Pepper, Cherry Coke Zero, or even sugar-free root beer for different flavor variations.
• If your blender is struggling, add the ice in smaller batches or add a small splash more of the soda to help it blend.

Pro Tips
- Reserve about 1/4 cup (60 ml) of the sugar-free soda before blending and stir it into the poured slushy right at the end for a fizzier drink.
- Pre-chill the blender pitcher and serving glasses in the freezer for 15 minutes — the slushy stays frozen and slushy noticeably longer.
- Pulse in short bursts rather than blending continuously; over-blending turns the mixture watery before you notice.

- Diet Dr. Pepper, Cherry Coke Zero, and sugar-free root beer all work in place of the sugar-free Coke if you want a different flavor.
