Prince Charles' wife Camilla - who was previously known as Camilla Parker Bowles- has revealed that her favourite thing to eat is raw peas. And she’s even managed to pass her obsession to her grandchildren, who Camilla claims gorge on them until they are “almost sick”.

Speaking about her love of peas, the 73-year-old royal said: “I like them cooked but I tell you what I really like - eating peas straight from the garden. If you take them straight from the pod they are delicious and really sweet. I take all my grandchildren down to the garden and they spend hours and hours eating peas. They eat and they eat until they are almost sick."

Camilla has five grandchildren from her own two children, as well as Prince William and Duchess Catherine's children, Prince George, Princess Charlotte, Prince Louis, and Prince Harry and Duchess Meghan's son Archie.

And she’s not the only royal with a particular penchant for unusual food items.

It was recently Princess Anne likes black bananas which she eats with a knife and fork for breakfast.

That’s according to Darren McGrady who was the Queen Elizabeth's head chef at Buckingham Palace for more than a decade, from 1982 to 1993.

Speaking to TODAY, Darren explained the unusual breakfast habits of the queen’s only daughter.

He said: “[Princess Anne] almost always preferred the bananas almost black - over ripe - because they digest easier.”

He also explained went into detail about some of the more unusual eating habits of the Royal Family generally, explaining that owing to etiquette they aren’t permitted to eat anything with their hands.

Apparently the top and bottom of fruit are taken off before the peel is “sliced down the middle” so it can be opened easily.

Darren also said that even guests are expected to follow the same etiquette when eating with the Royal Family. He said that anyone attending a royal banquet is provided with a: “dessert knife and fork, a small plate and a finger bowl”.
