With endless wealth and staff at her beck and call, you'd assume the Queen has a taste for the finer things in life.
However, her former private chef has claimed that she's eaten the same sandwich more or less every day since she was five years old.
Darren McGrady was the personal chef to Queen Liz, as well as Princess Diana and Princes William and Harry for fifteen years.
As such, he knows a thing or two about royal eating habits.
In a YouTube video in which he talks viewers through afternoon tea at Buckingham Palace, he spoke of the various sandwiches that are often on display at their garden parties.
McGrady explained that he would prepare a 'selection of different sandwiches' for the royal tent, and there's one filling in particular that's an absolute staple.
"The Queen was served jam pennies in the nursery as a little girl, she’s had them for afternoon tea ever since," he said.
"Simple – just bread and jam with a little butter, usually strawberry jam."
"We'd make the jam at Balmoral Castle with gorgeous Scottish strawberries from the gardens."
He'd then sandwich the bread together before cutting into circles and serving up, presumably on the finest silverware the UK has to offer.
Other sandwich fillings favoured by HRH include cucumber with a minty cream cheese, and tomato and cheese.
While the jam pennies are made using high quality ingredients – this is no Hartley's affair – people were shocked to discover the Queen has enjoyed such a simple dish for decades of her life.
Taking to the comments section, one viewer said: "A lot of that food seems so simple but just is reminder there’s so much naturally nice things, no need for all this Just Eat and Deliveroo!"
Others said they enjoyed the 'simplicity' of the recipe.
Some commenters weren't too keen on the idea, however, including this person who said: "The queen has eaten a jam sandwich every day since she was a kid.
"A bloody jam sandwich? Boring! If I was queen I’d definitely be more boujee than that."
This isn't the first time McGrady's opened up about the Queen's eating habits.
Earlier this year, the Royal chef revealed how Her Majesty likes to eat her fish and chips – and it's not what you'd think.
In another YouTube clip, he said that he would prepare the fish by baking it in bread crumbs rather than deep-frying it in batter.
"Fish fried in all that crispy rich batter was a little bit too much for her, she preferred a more refined fish and chips," he explained.
McGrady also disclosed that the Queen preferred her chips cut in neat ‘rectangles’ and stacked like a Jenga ‘tower’.
Oh, and mushy peas are also a no go for the royal – instead she enjoys a rich tarragon hollandaise sauce made with '90 percent butter'.
Who knew there was such precision when it came to fish and chips?
