While being a member of the Royal Family may seem glamorous, there are certain rules to follow, including dietary restrictions. Royal chefs are likely to be instructed to avoid two specific ingredients, one of which is a common kitchen staple.

The first of these must-avoid foods was revealed by Queen Camilla during her appearance on Masterchef Australia, where she surprised viewers by disclosing that the royals typically steer clear of garlic. When asked about the ingredients she and other Royal family members avoid, Camilla confessed: “I hate to say this, but garlic. Garlic is a no-no.”

This is partly because the smell and taste of garlic can linger, meaning it could be somewhat unpleasant for both the royal themselves and anyone they are meeting.

Another reason is simply that the late Queen Elizabeth II was not fond of this kitchen staple, nor was she particularly keen on onions. The second food item that the royals should avoid was disclosed by former Royal butler and etiquette expert Grant Harrold, reports the Mirror.

In a 2022 interview with Express.co.uk, he explained: “When dining, the Royal Family has to be careful with shellfish due to shellfish poisoning, due to their work schedules.

“Therefore you will not normally find this on the Royal menu.”

Despite the Royal family’s known avoidance of shellfish during official duties, they are not entirely averse to indulging in such delicacies at other times. The Queen Mother was known to be a big fan of the lavish seafood dish eggs Drumkilbo from The Dining Room at The Goring in London.

This decadent dish goes against the ‘no shellfish’ rule, being made up of white crab meat, mayonnaise, cucumber, roasted tomato, caviar, lobster, and quail’s egg with a runny yolk.
