The White House state dinner is set to take place next week with King Charles and Queen Camilla visiting from April 27 to 30. Darren McGrady, former personal chef to the late Queen Elizabeth II, Princess Diana, and her sons, Prince William and Prince Harry, predicts that the British royal family will expect "the best of America" to be served. McGrady also mentioned that the king would be particularly fond of local produce, particularly seasonal ingredients such as asparagus, artichokes, peas, spinach and broccoli. The White House will consult on dietary restrictions and preferences to impress the royals. Helenena Chard, British broadcaster and photographer, predicts herb-crusted organic Virginia lamb with copious amounts of humble vegetables.
