As the BBC reports, Coronation Quiche is the official dish of Coronation Big Lunches, hosted in communities across (and beyond) the UK. The recipe was created by royal chef Mark Flanagan, who previously served as Queen Elizabeth II’s chef and has presided over the royal kitchen for such events as Prince Harry and Meghan Markle’s 2018 wedding.
