(London) After the “coronation chicken”, the poached chicken served for the coronation of Elizabeth II in 1953, Charles and Camilla announced on Monday the recipe of their choice for their big day: a spinach, broad bean and tarragon quiche.

The king and queen consort, who will be crowned on May 6, have “chosen in person” the recipe for this quiche, a dish common in France but rare in the United Kingdom, which is presented on the Twitter account of the royal family.

She is expected to “encourage” Britons to get involved in the big coronation luncheon, the block party which will take place on the weekend of May 6, they hope.

The post is accompanied by a video showing a chef preparing the “coronation quiche”.

For the recipe, in addition to spinach, beans and tarragon, you must provide milk, fresh cream, eggs and of course, cheddar. It’s a dish that “easily adapts to different tastes and preferences,” boasts the royal family on Twitter. “To be eaten hot or cold with a green salad and boiled new potatoes”.

The 74-year-old king, who has posed for decades as a defender of the environment, and his 75-year-old wife, therefore chose a vegetarian recipe.

Will the quiche be as successful as Elizabeth II’s “coronation chicken” or “Queen Elizabeth’s Chicken”? This poached chicken coated in a creamy curry sauce, served at Buckingham Palace during a banquet for the Queen’s coronation in 1953, has become a classic of British gastronomy.

It is now offered as a prepared dish in supermarkets, as a filling for sandwiches or in several variations in cookbooks.

The coronation of Charles and his wife Camilla will take place on May 6 at Westminster Abbey, attended by around 2,000 guests. It will be followed in the weekend of neighborhood parties, a concert at Windsor Castle, west London. The British are also called upon to volunteer on Monday, May 8, which will be a public holiday.
