One of the things Queen Elizabeth II insists on is that royal chefs (past and present) must create menus in French. Tom Parker Bowles, son of Camilla, Duchess of Cornwall, reveals in Town and Country that it is "a tradition stretching back many centuries."

HuffPost suggests that the practice dates back to the 11th Century Norman conquest when French was the court language. Former butler Grant Harrold says, "If the queen hosts a dinner at Buckingham Palace, the menu is normally in French. [And] When she and the duke hosted dinner [...] it was done in their style, with the menus in French."

However, the menus from the weddings of Prince Charles to Camilla Parker Bowles and Prince William and Kate Middleton were written in English. Additionally, Mark Flanagan, the current royal chef reveals that the queen's Platinum Jubilee menu has been prepared in English "to make life easier," as the chef put it.
