Coronation chicken was created in 1953 by the florist Constance Spry and cordon bleu chef Rosemary Hume for the coronation of Queen Elizabeth II. Coronation chicken was very popular in the 1970s and is a retro classic dish. These days, you sometimes find a feeble version of this creamy, mayonaissy, mildly curried salad in sandwiches and wraps. Coronation chicken is easy to make and can be prepared in advance.
