One of the foods long forbidden by the late Queen Isabel herself, it is one of the most used ingredients in Portuguese cuisine. The queen hated the plant, which she also loved, but only in stews.
The ban has already been revealed by the Queen's daughter-in-law, Camilla Parker Bowles, Duchess of Cornwall, in an appearance on MasterChef Australia: "I hate to say it, but garlic... garlic is forbidden," said the current monarch.
A former royal chef went further and revealed that not only garlic, but also onions have a cross: "At Buckingham Palace, you don't cook with garlic or onions," revealed John Higgins. It is not known, however, why they are banned, whether because of the bad breath they leave in royal mouths, or because of their intense taste or smell.
In addition to these two essential ingredients, there is one type of food that must be avoided at all costs in the royal kitchen, in order to avoid any possibility of food poisoning.
Seafood is expressly forbidden during royal events or outings. "We don't want a member of the royal family to have a serious reaction to food poisoning. Especially if they're on an international trip," confessed King Charles III's former butler, Grant Harrold, quoted by The Express. But Charles doesn't always respect the rule: he's been photographed eating oysters more than once.
And it was King Charles III himself who banned one of the world's most expensive delicacies, foie gras, from all menus, in this case because of the way it is produced - it is made from a duck or goose liver that is abnormally enlarged due to a disease called hepatic steatosis.
But Isabella had a problem with other foods. The eternal queen, who rarely varied beyond her grilled or poached fish with vegetables and salad, disliked starches such as rice or mashed potatoes.
