The Queen's former head chef has revealed Princess Anne’s unusual preference when it comes to eating bananas.

Darren McGrady, who worked in the royal kitchens of Buckingham Palace from 1982 to 1993, also shared Princess Diana, Prince William and Prince Harry's bizarre habit when it comes to consuming pears, reports Bristol Live.

In an interview with TODAY, he said that after a pudding course, royals like to eat fruit.

Platters often include bananas, apples, pineapples, peaches, grapes and pears - and changes seasonally.

But the chef revealed that the Princess Royal enjoys eating her bananas ‘almost black’.

“Princess Anne almost always preferred the bananas almost black - over ripe - because they digested easier."

Due to an 'old tradition', members of the Royal Family are not able to eat any item of food with their hands.

This means most senior royals are forced to cut up fruit and eat it with a knife and fork, said McGrady.

“They [anyone present at the royal banquet] have a dessert knife and fork, a small plate and a finger bowl of water ... which some guests have been known to drink,” said McGrady.

And bananas aren’t the only fruit to receive special treatment.

While McGrady was working for the royal family, serving Princess Diana, Prince William and Prince Harry, they had an unusual way of enjoying pears.

“The purveyor would bring about 200 for us to choose the ripest by hand,” McGrady shared.

Then they "would slice off the top and eat it with a teaspoon like a boiled egg!”

He went on to say pineapples are ‘hollowed out,’ sliced, and put back into the pineapple so they can be eaten with a knife and fork.

McGrady has previously shared that the Queen enjoys four meals a day but only eats small portions at each.

The Queen is said to enjoy a cup of tea and biscuits, followed by cereal in the morning.

This is before moving on to a lunch of grilled fish with wilted spinach or courgettes.

She is also partial to a simple grilled chicken with salad.

Then, in the late afternoon, the Queen will have an afternoon tea.

It's understood the Queen is partial to steak at dinner, cooked well done.
