How to Make Your Own Slushie Mix

Directions

  1. 1Calibrate the refractometer per the manufacturer's instruction manual.
  2. 2Mix the slush syrup and stir it well before testing.
  3. 3Open the cover plate on the end of the refractometer.
  4. 4Use a pipette or liquid dropper to drop a few drops of slushie solution onto the angled prism.
  5. 5Close the cover plate tightly.
  6. 6Point the refractometer towards a light source and look through the eyepiece.
  7. 7To read the Brix scale, look for the point where the illuminated portion meets the dark portion.
  8. 8If the Brix reading is between 13% and 15%, your slushie mix is perfect.
  9. 9If the Brix reading is below 13%, add more sugar to the mix and try again.
  10. 10If the Brix reading is above 15%, add more water and try again.
  11. 11Clean the prism surface with a damp cloth after use and air dry.
  12. 12Mix premade slushie syrup with water, typically at a 1:4 or 1:5 ratio (1 cup syrup to 4 or 5 cups water), following the instructions on the mix.
  13. 13If adding other ingredients or syrups, replace a part of the premade syrup in the ratio (e.g., 1/2 cup flavoring syrup to 1/2 cup premade syrup).
  14. 14Test the sugar content with a refractometer before adding the mix to your machine.
  15. 15Mix neutral slush syrup with water to create the slushie base, then add desired flavors.

Tips

  • The ideal Brix reading for a slushie solution should fall between 13 and 15 degrees.
  • Always check the manufacturer's instructions for the recommended Brix level for your specific slushie machine.
  • Thoroughly check homemade slushie syrups to ensure they freeze correctly and don't damage your machine.
  • Alcohol affects the Brix reading and will cause it to be higher, meaning it will take longer to freeze.
  • Avoid anything with dairy ingredients unless your machine is rated to work with dairy.
