Irrespective of whether you’re a monarchist or a republican, any excuse to eat a tasty quiche is warmly welcomed. This quiche is the coronation dish for King Charles and was personally chosen by the King and Queen Consort. The quiche has a crisp, light pastry case and delicate flavours of spinach, broad beans, and fresh tarragon. If you’re time poor, you can buy a ready-made shortcrust pastry rather than making the pastry from scratch. You will need a 20-centimetre quiche tin for this recipe.
