🌀 Mixing Pro Tip

If your slushie is Too Thick and sticking to the sides of the blender, simply add a little More Sparkling Water. This will help loosen up the mixture, ensuring a smoother consistency and easier blending.

🥤 Serving Pro Tip

Enjoy the slushie Immediately after blending for the best texture and flavor.

Frequently Asked Questions
