Every year, the Queen gives up one of her favourite things during Lent.

The Christian period sees people go without something they love for 40 days to represent the 40 days Jesus spent fasting in the desert.

Traditionally Lent begins on Ash Wednesday, the day after Shrove Tuesday, or Pancake Day as it is more commonly known.

It ends on Holy Thursday evening, before the Evening Mass of the Lord's Supper.

During these 40 days, some might give up smoking or drinking, watching television or eating junk food.

But the Queen's one vice she goes without for Lent is something many of us might also consider giving up - chocolate.

Former royal chef, Darren McGrady has revealed that the Queen is actually quite the chocoholic, which is why she chooses this particular treat for Lent.

Darren worked for the Queen for 11 years

Speaking to OK Magazine, the chef, who worked for the royals for 11 years, said: "Her Majesty loves chocolate, but particularly dark chocolate.

"She gives it up for Lent and then looks forward to tucking into her favourite Bendicks Bittermints."

He continued to say that once Lent was over, boxes of the Queen's favourite chocolate would be provided for everyone to have a nibble on.

And these aren't the only chocolate treats that are enjoyed over the Easter weekend, the team in the kitchen at Windsor Castle also make their own Easter eggs too.

"Those for the adults would be decorated in pretty sugared flowers and placed on the table, so people could break off pieces," explained McGrady.

"There were no Easter egg hunts back then but we’d make special novelty eggs for the children."

McGrady went on to share a hilarious memory of one particular chocolate egg that he made - back when Prince William was just a young boy.

The egg was based around the Hickory Dickory Dock nursery rhyme, with a clock on top striking one and a sugared mouse peeking out of a hole.

He added: "We sent it up to the nursery on the silver tray, but 15 minutes later the Footman brought it back.

"He said, 'Nanny asked me to return this. Prince William has just stood on a chair and bitten the mouse’s head off, frightening Beatrice and Eugenie.'

"We had to quickly make another mouse, pop it in the hole and send it back to the nursery. I think Nanny put the egg out of William’s reach to make sure it didn’t happen again!"
