Start by ordering a Grande Green Tea Frappuccino made with coconut milk.
Ask for a scoop of the ginger turmeric powder and 1 pump of the pineapple syrup.
And finally, ask for more matcha powder and ginger powder on top of the drink.
And that's it! You will have your very own Polyjuice Potion Frappuccino for all you Potterheads like me!
