Prince Philip was a known foodie, so much so that he thoroughly enjoyed cooking for himself, the Queen and his family on various occasions. In the book Dinner at Buckingham Palace by former royal footman Charles Oliver, the Duke is said to have brought his electric glass-lidded frying pan wherever he went, preparing breakfast and supper snacks as his specialties. Former royal chef Darren McGrady also said on his YouTube channel that during summer stays at Balmoral, Prince Philip would often grill several days a week. Though most of his dishes were simple, he didn't shy away from experimenting with different flavors and new preparations.
