Speaking to TODAY, Mr McGrady explained one strange rule – that no hands are allowed to touch food at a royal banquet.
Mr McGrady said the rule makes it difficult for the Royal Family to eat most kinds of fruit – a common dish served at the end of the meal.
He explained that using a knife and fork, members of the Royal Family would slice off the top of a pear “and eat it with a teaspoon like a boiled egg”.

Mr McGrady added that the rule of never eating with your hands also extends to anyone else at a royal banquet.
He added that all guests are provided with a “dessert knife and fork, a small plate and a finger bowl”.
Fans of the royal family are always surprised to hear the sometimes complicated requests sent down to the royal kitchen.
Princess Anne is one such royal family member who had a peculiar request for food.

The Princess Royal eats a bowl of fruit every morning, which usually involves a banana, but according to Mr McGrady she prefers it to be over ripe.
“[Princess Anne] almost always preferred the bananas almost black — over ripe — because they digest easier,” admitted Mr McGrady.
He added that bananas are one of the most difficult fruits for the royals to eat.
He again explained that the ends of the banana are cut off before the peel is “sliced down the middle” from end to end so that it can be unpeeled.

Mr McGrady also admitted that grapes are one of the easiest fruits to eat.
He said: “Grapes are the most popular as they are the easiest to eat and cut into smaller bunches of four or five grapes.”
