Chocolate Cauldrons are boxed chocolates that are filled with Firewhiskey and presumably shaped like cauldrons. Romilda Vane gave Harry Potter a box that she had spiked with Love Potion in 1996. On March 1, they were eaten by Ron Weasley who mistook them for birthday sweets.
There are most likely eight in a package, since when Ron Weasley ate four Cauldrons with Romilda's love potion in them, Harry said, "You just ate half a box of Chocolate Cauldrons."
Behind the scenes
- In the book, Ron eats "about half a box" of these, but in the film, he eats the whole box.
- The Wizarding World of Harry Potter sells Chocolate Cauldrons. They are hollow milk chocolate cauldrons, with a green mashmallow "foam".
