5. Pumpkin Pasties and Juice
Though juice and pasties (a filled pastry case for you American Muggles) have been around for quite some time, author J.K. Rowling's popularization of the pumpkin-flavored variety can be owed entirely to Pottermania. And in the Harry Potter franchise, pumpkin is always in season–Harry's first introduction to pumpkin pasties happens on his first trip over on the Hogwarts Express (and every subsequent trip after), and pumpkin juice is always available at breakfast time. And with Harry Potter's faint Halloween-y theme (you know, witches and goblins and shit), gorging on pumpkin fare seems like a fitting way to bid the franchise adieu.
4. Puking Pastilles
The scourge of Harry's fifth year, the Puking Pastilles (and other treats from the Skiving Snackboxes, like the Nosebleed Nougat) cause the ingester to become immediately (and rather violently) ill. Invented by Fred and George Weasley, the pastilles were meant to help students fake illness to get out of class–once students were safely back in their dormitories, they would swallow the antidote and have the rest of the day to themselves. For Muggles, it's reccomended to make them without the vomit-inducing aspect–unless vomiting is what you're going for, in which case, I reccommend using Cuervo.
3. Chocolate Frogs
These frog-shaped chocolates come with a few surprises–for one, they come with a moving, tradeable card of notable witches and wizards (nifty). And they come to life (yikes!). The frogs make their debut in the first Potter film, Harry Potter and the Sorcerer's Stone, and are one of the first (if not the first) magical food that the boy wizard encounters. The chocolate frog cards enable the trio to discover the identity of Nicholas Flamel, leading to the realization that the Sorcer's Stone is being kept in the bowels of Hogwarts. Besides being useful, they look pretty tasty (if you can catch one, that is).
2. Bertie Botts Every Flavor Beans
Just when Jelly Belly seemed to suffer a popularity dip, they struck on Wizarding gold. Bertie Bott's Every Flavor Beans have flavors ranging from strawberry to gravy to rotten eggs (yum). Potter fanatics can get a thrill from ingesting Dumbledore's favorite sweet treat on the chance that it might taste like earwax or dirt. It's pretty ingenious, and a testament to the mass appeal of Harry Potter–how else could you get hordes of people to buy shit-flavored candy?
Top marks to Butterbeer for bringing together the greatest things teens love: butter, beer and underage drinking (seriously–Harry's 13 when he first has some). Teacher-approved and Muggle-beloved (it sells like crazy over at the theme park in Orlando, though it's ironically stripped of both butter and beer for mass appeal), this butterscotch-colored ale made its first appearance in Harry Potter and the Prisoner of Azkaban and is a longtime Potter mainstay. Plus, did we mention it has alcohol?
