Polyjuice Potion

Jump to Recipe
Spread the love

When I started my research for a polyjuice potion recipe all I could find were green colored drinks. None of this makes any sense, because we true fans know, that polyjuice potion is not really a liquid form. It is a greyish goo with chunks of lacewing flies, leeches, flux-weed, and knotgrass. In addition to powdered horn of Bicorn, shredded skin of Bloomslang, and pieces of the person you want to change into (hopefully not toenails- Ron). I want to stay true to the books, so, while I am giving you something in a glass, it is not a drink. It is a mousse, mixed with fun bits of edible cookie dough, toffee, and chocolate chips.

What do you need for your Polyjuice Potion Recipe?

For your polyjuice potion you will not need toenails or bloomslang, but you will need the following:

  1. Edible Cookie Dough (recipe will follow)
  2. Chocolate Chips
  3. Toffee Bits
  4. 1 cup milk (I used 2% but you can use whole should you choose)
  5. 16 oz yogurt
  6. 1.5 tablespoon vanilla (I used bean paste)
  7. 1 cup + 2 tablespoon sugar
  8. 2 packets of gelatin (I used knox)
  9. 1 cup heavy cream

Recipe for edible cookie dough:

  1. One stick butter- at room temperature
  2. ½ cup (¼ cup brown sugar + ¼ cup white)
  3. 1 ¼ cup flour
  4. 2-3 tablespoon milk or cream
  5. toffee bits
  6. chocolate chips
  7. 1 teaspoon vanilla
  8. 1 teaspoon almond

How do you make it?

First, you are going to make your edible cookie dough. What I love about this recipe is that it is egg free (so no worries about salmonella) and it is not too sweet because you will be adding it to something sweet.

  1. Beat your butter in your mixer with the paddle attachment.
  2. Add your sugars, and cream them together. Allow them to beat together for about 3-5 minutes because it will become light and fluffy.
  3. Once it is all nice and fluffy, you are going to add your flour. It is going to be really clumpy and appear to not be turning into a dough. This is when you add your milk or cream.
  4. Once your milk and or cream have been added, it should be coming together, add your vanilla and almond extracts, along with the chocolate chips and toffee bits.
  5. Voila! Edible cookie dough- set this aside while you make your mousse aka polyjuice potion!

How to make your mousse:

  1. In a pot, take your one cup of milk, 2 packets of gelatin, and vanilla, and whisk together.
  2. Place it on the stove on medium heat, you do not want this to boil. I repeat- do not boil. You simply want this to simmer.
  3. Whisk this while it continues to simmer- once you get a good simmer- remove your pot from the heat and allow it to cool.
  4. Take your 16 oz of yogurt or sour cream and mix it together with the sugar. You want it to come together so not the sugar is not visible and it appears smooth.
  5. Meanwhile, place your cream in your mixer and beat your whipping cream to stiff peaks.
  6. Once your cream is at stiff peaks, add it ⅓ at a time to your bowl with your yogurt. It is at this point that you may want to add the grey food coloring to match the color from the movies. Once all of your cream has been added to the bowl, move the entire mixture back into the bowl for your stand mixer.
  7. You are going to put your mixer on slow and slowly add your mixture with the gelatin in it. As it pours in it will add the gelatin to your mixture.
  8. Decide what glasses you want to serve your polyjuice potion in, and add your cookie dough along with extra chocolate chips, and toffee.
  9. Pour your "potion" recipe over this in the glasses and place in the fridge for a minimum of 3 hours. Chilling it will allow your polyjuice potion recipe to set!

Why should you make this
Polyjuice Potion Recipe?

It is a really big moment in the series when Harry, Ron, and Hermione make and take the potion. Much to the dismay of Hermione, her turning into a cat was not part of the plan, but none the less, the results they wanted were obtained! The recipe alone is delicious. You get the tangyness of the yogurt and sweetness from the cream, cookie dough, and toffee, plus, you get the fun nostalgia. You also can take pride in the fact that you didn't make a green drink like Pinterest wanted you to do and did something much more akin to the story.

I hope you enjoy it!
Always,
L
