The following are food and beverages unique to the wizarding world:

Magical sweets

Multitudes of sweets are referred to in the stories; many have violent or bizarre side effects, especially those created by Fred and George Weasley. Most sweets can be found in the sweetshop Honeydukes or on the Hogwarts Train sweet trolley. Dumbledore seems to be partial to these as he often uses their names as passwords.

Chocolate Frogs are, as the name suggests, frogs made of chocolate, and are very popular wizarding sweets. They are each packaged with a collectible card displaying a magical picture and brief biography of a famous witch or wizard of medieval to modern times. Cards named in the Harry Potter series include wizards such as Merlin, Dumbledore, Nicholas Flamel and the four founders of Hogwarts. According to a webchat with the author, Harry and his friends are eventually featured on a series of Chocolate Frog cards, with Ron calling it "his finest hour".

Some of the most notable magical sweets such as Bertie Bott's Every-Flavour Beans, Skiving Snackboxes and Cockroach Clusters have been manufactured in real life, mainly by the Jelly Belly candy company. They have produced real versions of Bertie Bott's Every-Flavour Beans odd flavours in and out of the market since 2001. Apart from some "regular" flavours, the company also produces several "unusual" flavours mentioned in the books. Other flavours include bacon, dirt, earthworm, earwax, vomit, rotten egg, sausage, pickle, toast, grass and soap.

A description of Honeydukes in the third book says that the store sells candies called Coconut Ice, Ice Mice (which make your teeth chatter and squeak), Fizzing Whizbees, Pepper Imps (which allow you to breathe fire on your friends), Sugar Quills, Cockroach Clusters, self-flossing mints, Drooble's Best Blowing Gum (which make a room fill up with bluebell-coloured bubbles which wouldn't pop for days), Peppermint Creams shaped like toads (which hop in your stomach), Exploding Bonbons, Jelly Slugs, Acid Pops, and blood-flavoured lollipops.

Butterbeer

Butterbeer is the drink of choice for younger wizards. Harry is first presented with the beverage in Harry Potter and the Prisoner of Azkaban. Although house-elves can become intoxicated on Butterbeer, the amount of alcohol contained in Butterbeer has a negligible effect on witches and wizards. J.K. Rowling said in her interview to Bon Appétit magazine that she imagines it "to taste a little bit like less-sickly butterscotch". Butterbeer can be served cold or hot, but either way it has a warming effect.

The earliest reference to buttered beer is from The Good Huswifes Handmaide for the Kitchin, published in London in 1588. It was made from beer, sugar, eggs, nutmeg, cloves and butter. Another old recipe for buttered beer, published by Robert May in 1664 from his recipe book The Accomplisht Cook, calls for liquorice root and aniseed to be added. British celebrity chef Heston Blumenthal recreated the drink for his show "Heston's Tudor Feast".

It was announced in April 2010 that a drink named after butterbeer would be sold in the theme park The Wizarding World of Harry Potter at Universal Orlando. The beverage is also sold at the Warner Bros. Studio Tour London. It has a sweet taste and is a non-alcoholic beverage. It was taste-tested by J. K. Rowling herself. According to Neil Genzlinger, a staff editor on the culture desk of The New York Times, the beverage "is indistinguishable from a good quality cream soda".

Firewhisky

Firewhisky is a type of alcohol that wizards under the age of seventeen are not allowed to drink; however, this rule is not always followed. Firewhisky is described as burning the drinkers' throats as they consume it.

It can be seen as a very strong whisky, and by all intents is used as such. The characters drink it in the last book when Mad-Eye Moody dies in flight, to numb the shock and toast to his life. Hagrid also drinks it, although in much larger quantities.

Pumpkin juice

Pumpkin juice is a cold drink favoured by the Wizarding World, and among the students at Hogwarts School of Witchcraft and Wizardry. It is drunk at any occasion, such as breakfast, lunch, at feasts or on other occasions. It seems to have taken on the same role that orange juice has to Muggles.

Pumpkin juice is readily available, and can be purchased on the Hogwarts Express. Severus Snape threatened Harry in his fourth year that he might slip Veritaserum in his morning pumpkin juice while believing that Harry had stolen some of Snape's potion ingredients. Prior to a Quidditch match in his sixth year, Ron Weasley believed that Harry had slipped Felix Felicis into his morning juice to help him play perfectly.

Pumpkin juice is one of several speciality beverages developed for Universal's Wizarding World of Harry Potter theme park (along with butterbeer, see above). According to a preview by The New York Times' Neil Genzlinger, "Pumpkin juice (in a cute, pumpkin-topped bottle) is far more interesting [than the park's butterbeer], perhaps because the actual pumpkin content seems minimal – it’s more like a feisty apple cider with a little pumpkin thrown in."

Gillywater

Gillywater is a beverage sold in the Harry Potter universe. Professor McGonagall drinks this in Harry Potter and the Prisoner of Azkaban.
