As a little girl, Queen Elizabeth was served what's known as Jam Pennies, jam sandwiches, in the royal nursery. And according to a former royal chef, Her Majesty has eaten them every day for 91 years.
The Sun reports that Darren McGrady worked for the royal family for almost two decades and has since revealed some of the Queen's favourite dishes and daily requests.
Of her penchant for Jam Pennies, McGrady explains they're a simple sandwich of "... bread and jam with a little butter – usually strawberry jam.
"We'd make the jam at Balmoral Castle with the gorgeous Scottish strawberries from the gardens."
Another former royal chef, Owen Hodgson, has also shared that the monarch is partial to a savoury sandwich said to be popular among Brits: tuna and mayonnaise.
