Petunia's Pudding

From UnknowableWiki

Petunia's pudding is a pudding that Petunia Dursley makes to impress Mr. Mason, a potential customer of Vernon Dursley's company, Grunnings, and his wife (CS2). It is most likely a summer pudding and is decorated with whipped cream and sugared violets.

The house elf Dobby uses Petunia's pudding to blackmail Harry. He levitates the pudding and threatens to let it fall if Harry doesn't promise not to return to Hogwarts for his second year. When Harry refuses, Dobby lets the bowl crash onto the Dursley kitchen floor and Disapparates, leaving Harry to face the wrath of the Dursleys and the Improper Use of Magic Office (CS2).
