Britain's King Charles III and his wife Camilla announced their choice of spinach, beans and tarragon quiche to be served at the expected coronation party on May 6, after the chicken was present during the coronation of Elizabeth II in 1953.

Charles and Camilla "personally" chose the famous quiche in France, but not so popular in the UK. This dish was discussed on the official royal family account via Twitter.

Charles and his wife hoped their choice would "encourage" Britons to take part in the grand coronation lunch, a celebration that takes place on Saturday and Sunday, May 6 and 7.

The message was accompanied by a video showing a chef preparing the quiche for the coronation party.

The recipe includes several ingredients, including spinach, beans, tarragon, milk, liquid cream, eggs and cheddar cheese.

And the royal family confirmed on Twitter that this dish "is suitable for all tastes, and it can be eaten hot or cold, with vegetable salad and boiled potatoes."

During the coronation of Elizabeth II in 1953, a dish of chicken was served with creamy curry sauce, and it became one of the traditional dishes in British cuisine.

The coronation of Charles and his wife Camilla will be held on the sixth of May in Westminster Abbey, in the presence of about two thousand guests. This weekend, there will be celebrations and a concert at Windsor Castle, west London.
