She's known for having modest tastes, but anyone cooking for her needs to help prepare some of the world's extravagant banquets.
The Royal Household is advertising for a new sous chef who can make meals fit for a Queen.
The NZ$45,000-a-year chef will be based at Buckingham Palace but must be prepared to travel to other Royal residences and have a "good understanding of kitchen French".
The job description, posted on the Buckingham Palace website, says: "From state banquets for 200 to lunches for two; and from canapé receptions for 800 to staff restaurant meals; our chefs prepare it all to the same exceptional standards.
"In this hands-on position you will help to lead and train the junior chefs to deliver quality fresh food to the highest standards, and you will also take charge of the kitchen operation when working from smaller kitchens and when deputising for senior colleagues.
