Queen Elizabeth II is a well-known food fanatic. As Travel + Leisure previously reported, the Queen is quite fond of chocolate biscuit cake — so much so that she refuses to travel even a short distance without a slice of it with her.

But it turns out, there is one ingredient the Queen despises so much it has been entirely banned from Buckingham Palace. And that loathed food is garlic.

“The Queen is a wonderful lady,” Chef John Higgins, a former chef at Buckingham Palace who cooked for the Queen, told the National Post. “The royal family are wonderful people but they’re missing out on garlic because at Buckingham Palace you don’t cook with garlic. I suppose, in case you get the royal burp.”

According to Higgins, the garlic ban is so well-known that if a chef claims to have ever cooked for the Queen, he can check for a lack of garlic as a marker of authenticity.

Beyond garlic, Higgins also shared that the Queen is particular about the way food is prepared for her beloved corgis. In fact, it’s a lesson Higgins said he learned the hard way after putting rabbit through a grinder, rather than hand-dicing the meat.

“That was a no...the Queen sent it back and I had to do it all over again.”

And Higgins, like chefs before him, verified that the Queen does indeed have a rather strong sweet tooth.

“The Queen really enjoyed mangoes. She could tell you how many mangos were in the fridge at Buckingham Palace,” he said, adding that she has also been known to indulge in his chocolate mousse.

“Trust me. The plates were clean when they came back from the royal family,” he said.
