About Polyjuice Potion

Halloween is the absolute best holiday to have pop culture fun with, and this polyjuice potion recipe is just another delicious way to enjoy a themed party or movie night.

And the best part? This festive drink is not only delicious, but it’s also family-friendly as well, because it is alcohol-free.

Now, you can still add alcohol if you want to (and I have a few suggestions on that in the notes below), but as it’s currently written, this recipe is meant to be delicious for all ages.

So, rejoice! Now all the little goblins and ghouls (or Gryffindors, Ravenclaws, Hufflepuffs, and Slytherins!) at your soiree can get in on the Halloween party fun as well. Plus, you know kids love anything that’s 1) super creepy and 2) looks like what all the adults are drinking.

What’s in this polyjuice potion?

To whip up a batch of this fun, witch-themed punch, you’ll only need the following:

  • Lime sherbet – Delicious flavor and gives the drink it’s creamy look.
  • Sprite and Ginger Ale – These turn the ice cream into a drinkable punch and the carbonation from the soda reacts with the ice cream to create a frothy foam on top.
  • Green food coloring – This is optional, but can help give the drink a darker green hue, if you’d like. I chose green because it went with the lime sherbet and the overall “witchy” look, but you could go crazy with a bunch of different colors. By the time you add the soda, any color that the sherbet had will have become very pale and subdued, so you wouldn’t need to add a lot of food coloring to go with other spooky colors like red, purple, or orange.
  • Whipped cream – A totally optional topping, but can be great for looks if you’re using a drink dispenser, as the foam from the drink will not transfer very well through the spigot. The whipped cream helps reproduce the just-brewed-from-a-cauldron vibe.

Can you make this drink in advance?

This recipe essentially comes down to two ingredients – ice cream and soda – and because of that, I wouldn’t recommend preparing it in advance. The soda will become flat after a few hours, killing the foam that generates when the soda hits the ice cream.

For best results, plan on mixing this drink just before serving.

How long is polyjuice potion good for?

Once prepared, I would recommend enjoying this drink the same day that it’s made. It should remain good for a few hours, at least.

Can you add alcohol to this drink?

This recipe is designed to be alcohol-free, but if you simply must have a little punch in your punch, I’d recommend adding 1 or 2 cups (taste testing inbetween!) of any of the following: Midori, tequila, or a lime-flavored vodka.

notes & tips for this lime sherbet punch

  • In the video and photos for this recipe, I used plastic snakes and plastic spiders as props. They were thoroughly washed & scrubbed before being added to the punch (which I highly recommend you do as well!) and were added just for a bit of creepy fun. If you’d like to do the same with your polyjuice potion, please check whether or not there will be small children at your party – we wouldn’t want anyone to accidentally swallow some plastic! If you will have small children and still really want to use the props, try hunting down a drink dispenser with a spigot (like the one pictured). That way no snakes or spiders will end up in anyone’s drink but you can still get the creepy vibe whenever the drink is stirred.
