Frozen Coke Zero

Directions

1. 1Measure out the Coke Zero into a large clean pitcher.
2. 2Gradually add the liquid allulose, whisking slowly to control the carbonation fizz and prevent overflow.
3. 3Stir in the fresh lemon juice to balance sweetness and aid crystal structure.
4. 4Pour the carbonated mixture directly into the Slushi container.
5. 5Select the SLUSH program, adjusting the temperature down one bar from default.
6. 6Let the machine spin for 35 to 45 minutes, then dispense immediately.

Tips

• Pour your Coke Zero and allulose mix directly into the slushi bowl at room temperature, no pre-chilling needed. The machine does the freezing work.
• Check the consistency around the 30-minute mark by looking through the bowl. You want a soft slush that flows from the tap, not a solid block.
• Use fresh lemon juice squeezed that day rather than bottled for the brightest flavor, since the citrus cuts through the sweetness nicely.

Variations

• Swap regular Coke for Coke Zero if you want more sweetness, though you may want to reduce the allulose slightly.
• Add a splash of fresh lime juice instead of lemon for a different citrus angle, keeping the total liquid volume the same.
• Try a mix of half Coke Zero and half ginger ale with the same amount of allulose and lemon for a spicier twist.

FAQ

Can I use a different sweetener instead of liquid allulose?

You can try monk fruit liquid sweetener as a one-to-one swap, but allulose works best because it freezes to the right texture. Granulated sweeteners won't dissolve properly in the liquid base.

My slushi came out too thick or icy. What went wrong?

The machine may have run too long. Check around 25-30 minutes next time instead of waiting the full hour. If it's already thick, add a splash of Coke Zero and pour it back in to churn briefly.

How long does the finished slushi last if I don't drink it right away?

Once you stop the machine, the slushi will start separating and refreezing within 30 minutes at room temperature. It's best consumed fresh from the tap.

Can I make it less sweet?

Yes, reduce the allulose by half and increase the lemon juice slightly for more tartness. You'll need to run the machine a bit longer since there's less sugar to help with freezing texture.
