LONDON -- Queen Elizabeth II has eaten jam sandwiches every day since she was a toddler, according to her former private chef.

Darren McGrady claims on his YouTube channel that the monarch favours a strawberry preserve made from fruits picked in her Balmoral Castle grounds in Scotland.

"The Queen was served jam pennies in the nursery as a little girl. She's had them for afternoon tea ever since," he says in a recently surfaced video . The sandwiches are made from bread with a little butter and a spread of jam, then cut out into circles the size of an old British penny.

As part of the genteel tradition of afternoon tea, McGrady, who says he was a chef to the Queen for 11 years, also revealed the monarch's solution to a familiar quandary for British scone lovers: jam first or cream?

"The Queen was always jam first," he said in a separate video. "The jam went on followed by that delicious, clotted cream."

As well as the preserve, the 96-year old monarch has always been partial to fresh strawberries. "The Queen would eat strawberries three or four nights a week in Balmoral if they were in season," he says.

But woe betide anyone who tried to give her out-of-season berries. A January batch at the supper table would mean "off with your head," joked McGrady.

The Palace would not comment on the Queen's sandwich preferences.
