“Plate… surprise” will be offered by King Charles and Royal Wife Camilla to the guests for their coronation.

After the “coronation chicken” served by Queen Elizabeth II in 1953, Charles and Camilla announced today Monday the recipe they had chosen for their own enthronement: the… “coronation quiche lorraine”, i.e. a vegetarian quiche lorraine with spinach, beans and tarragon.

The king and royal wife, whose coronation is scheduled for May 6, chose the recipe themselves, which they also presented in a short video on the royal family’s Twitter account. Quiche Lorraine is a very common dish in France, but not common in Britain.

In addition to spinach, baked beans and tarragon, the recipe includes milk, cream, eggs and, of course, cheddar cheese, so it’s definitely not vegan. It is a dish that is “easily adapted to everyone’s different tastes and preferences” and can be eaten “hot or cold, with a green salad and potatoes”.

It is currently unknown whether Charles and Camilla’s… unconventional vegetarian quiche Lorraine will be as successful as Elizabeth’s creamy curry chicken, which is now considered a classic of British cuisine and can even be found in Super Market.
