The bizarre teatime sandwich rule Queen Elizabeth II likes to follow

There’s no denying the Windsors follow a hefty rulebook full of dos and don'ts ... including not showing public displays of affection and not eating garlic, to only wearing nude nail polish and keeping quiet on political opinions.

Yes, it's a lot to take in.

And now we've discovered another rule that Queen Elizabeth II likes to follow - and it’s all to do with her sandwiches.

According to the monarch's former royal chef Graham Newbould, point-edged food is not allowed at Her Majesty's table, as part of a tradition started by her royal ancestors.

During his time working for the 95-year-old monarch, Newbould revealed the Queen never ate sandwiches shaped with points - instead she is served small 'jam penny' sandwiches at afternoon tea.

Speaking in the documentary Secrets of the Royal Kitchen, he said: "The royals never have square sandwiches because tradition has it that anyone presenting them with pointed-edged food is trying to overthrow the throne of England."

Another former royal chef, Darren McGrady – who cooked for the Queen for 11 years - previously discussed her fondness for round sandwiches.

"One of her favourites is Jam Pennies, they're just bread and jam," he continued, pointing to a picture of small, round disks of white bread with a layer of strawberry jam in the middle."

Fascinating!
