Syrup

• Type: Potion Ingredient, Foodstuff
• Notable Varieties: Syrup of Hellebore, Fig Syrup

Syrup in the wizarding world is a general term for a thick, viscous liquid used in various contexts, from complex Potions to common culinary treats. Its properties can range from mundane and sweet to potent and dangerous, depending on its core ingredients. Two specific types of syrup are mentioned by name:

• Syrup of Hellebore: A crucial ingredient in the Draught of Peace. According to Potions Master Horace Slughorn, this ingredient must be handled with extreme care. Adding too much is a common mistake that can cause the drinker to fall into a deep and sometimes irreversible sleep. This indicates that Hellebore, when concentrated in syrup form, is a powerful soporific or poison.
• Fig Syrup: Mentioned by the eccentric knight Sir Cadogan as a potential password for the Gryffindor common room. He suggests “a flagon of distilled fig syrup,” implying it is a known, if perhaps somewhat uncommon, substance. Its properties are not detailed, but its context suggests it is a simple, non-dangerous substance.

Syrup is also a common component in food and drink, providing sweetness and flavour. It is a key ingredient in desserts like Syrup Tart and is noted as a flavour in beverages like the elf-made wine served by Dobby.

Syrup is mentioned in several instances, highlighting its dual role as both a mundane substance and a critical magical ingredient.

• In Harry Potter and the Goblet of Fire, Sir Cadogan's suggestion of fig syrup as a password serves as a moment of comic relief and adds texture to the everyday culture of the wizarding world.
• In Harry Potter and the Half-Blood Prince, Syrup of Hellebore becomes a focal point during one of Harry Potter's Potions lessons. By following the notes in the Half-Blood Prince's textbook, Harry correctly prepares his Draught of Peace, prompting Horace Slughorn to lecture the class on the dangers of misusing the syrup. This moment showcases Harry's growing reliance on the mysterious Prince's annotations.
• Later in Half-Blood Prince, Dobby brings Harry Potter and Ron Weasley a bottle of elf-made wine that is described as tasting partly of syrup. This reinforces its use as a common flavouring in the magical community's food and drink.

• Hellebore is a genus of real-world herbaceous perennial flowering plants. Many species of Hellebore are poisonous, containing alkaloids that can cause severe symptoms if ingested, which aligns with the dangerous properties of Syrup of Hellebore in the books.
• While the books mention “syrup tarts,” J.K. Rowling has stated in interviews that Harry Potter's favourite food is treacle tart, a very similar traditional British dessert made with golden syrup (J.K. Rowling interview).
