So what does the Queen actually choose to eat when pleasing herself? Her former chef, Darren McGrady, who later became head chef to Diana, Princess of Wales, recalls she would always be involved in menu planning and everything has to be approved by her. This includes banquets held at the Royal households for other heads of state.
To make her recipe choices for these, the Queen keeps a book of menus to help recall things she has liked in the past. All food is cooked ‘Palace style’. Classic recipes have excess onions removed, because the Queen dislikes them; likewise, garlic and heavy seasoning never make an appearance at her table.
Menus are always written in French, a practice harking back to pre-war beliefs that French dishes are either better than English or simply look more appetising on the page.
The Queen’s daily diet is mainly carbohydrate-free, consisting of grilled meat – usually chicken – or fish (she loves sole), served with two vegetables or a bowl of salad. Fruit follows. She is not keen on wine, but finishes the day with a Dubonnet and gin cocktail.
