Why This Recipe Works

  • Kid-friendly, non-alcoholic version of polyjuice potion. There are some alcoholic versions of this potion on the internet, but I wanted a simple and kid-friendly option so that everyone at your Harry Potter party or Halloween party can enjoy this magical drink! 
  • 3 ingredients. You only need 3 ingredients to make this Harry Potter polyjuice potion drink! 

Ingredient Notes

Ingredients used to make Polyjuice Potion on a gray background: lime sherbet, green food color, Sprite.
  • Lime Sherbet: If you have a hard time finding lime sherbet, you can use rainbow sherbet. Just note that the green color won’t be prominent so you’ll want to add the food coloring. Even with the food coloring you won’t have as vibrant of a green color so keep that in mind. 
  • Lemon Lime Soda: You can use Sprite or 7-Up.
  • Green Food Coloring: This is optional, but helps the drink be a more vibrant green. If you are using rainbow sherbet, I would definitely add the green food coloring since rainbow sherbet mixes up to be a very blah color haha. 

Step-by-Step Instructions

  1. Combine the polyjuice potion ingredients. Add the lime sherbet to a large pitcher. Pour the lemon lime soda on top and add a few drops of green food coloring. Stir to combine. 
  2. Serve. Serve this magical potion chilled as is or with whipped cream on top! Enjoy! 

Recipe Tips

Keep the drink chilled. I let the sherbet sit at room temperature for about 15 minutes before scooping, this makes it easier and helps mix into the soda a bit easier.

If you can’t find lime sherbet, you can use rainbow sherbet and then add the green food coloring. You won’t have such a bright green color, but it will work! 

Feel free to add the ingredients to a large punch bowl and serve that way instead of in a pitcher. 

Make Ahead, Storing, and Freezing

Due to the lime sherbet and carbonation, it’s best to make this polyjuice drink just prior to serving it. 

Store any leftovers in the fridge for up to 1 day (I doubt you’ll have leftovers! It’s so yummy people will eat it up!) .

While you can freeze polyjuice potion, you’ll most likely lose the fizzy carbonation from the Sprite when doing so.

Recipe FAQs

What is polyjuice potion?

Polyjuice potion is the most complicated potion Hermione brews in the second Harry Potter film, Harry Potter and the Chamber of Secrets, from the book Moste Potente Potions, to find out who the heir of Slytherin is (the person opening the Chamber of Secrets and attacking muggle borns). The potion enables the drinker to change into the physical appearance of another person by putting part of the person (usually some of the person’s hair) into the potion.

What are the ingredients for polyjuice potion?

J.K. Rowling writes that the potion ingredients are lacewing flies, leeches, powdered horn of a Bicorn, knotgrass, fluxed, and boomslang skin. This recipe doesn’t contain any of those ingredients — just Sprite, lime sherbet and green food coloring. This polyjuice potion recipe is to merely remind you of that famous wizarding potion!

Is polyjuice potion green?

While the drink has a murky greenish brown color in the movie (the potion will go through a color change in reaction to different hairs added), there is an iconic scene of Hermione pouring an ingredient into her potions cauldron while making the potion in Moaning Myrtle’s bathroom. The ingredient is a green color. As such, much of the muggle world has since made Harry Potter-inspired polyjuice potion recipes that are green.

How long does polyjuice potion last?

According to J.K. Rowling as published on the Wizarding World, depending on how well it is brewed, the potion can last anywhere from 10 minutes time up to 12 hours time. Hermione, Harry, and Ron had 60 minutes when they transfigured into the partial cat, Gregory Goyle and Vincent Crabbe. This polyjuice potion recipe will last for a few hours before the carbonation wears off. 

When was polyjuice potion was used in the Harry Potter series?

Chamber of Secrets when Hermione brewed it; Goblet of Fire when Barty Crouch Jr. turned into Mad-Eye Moody; Half-Blood Prince when Professor Slughorn showed it along with Amortentia and Felix Felices (which Draco Malfoy stole to have Crabbe and Goyle impersonate students to stand guard while he fixed the vanishing cabinet); Deathly Hallows when Harry escaped the Dursley during the battle of the seven Potters against the death eaters, when Harry showed up as fake cousin Barny Weasly to Bill and Fluer’s wedding, when Harry, Ron and Hermione used it to get into the Ministry of Magic, and when Hermione become Bellatrix Lestrange to break into Gringotts.
