Everyone knows that the main ingredient in any celebration is, of course, a cake!
A ship commissioning also abides by this rule.
That is why in May the Royal Navy tasked 3D Bakers, in Scotland, to bake a cake for HMS Queen Elizabeth's commissioning ceremony.
And they have certainly made a cake fit for a queen.
They created an eight-foot replica of HMS Queen Elizabeth.
Over 100 hours went into the creation and the cake weighs a whopping 150kg, it was made using 7kg of flour and over 1670 eggs!
David Duncan, the founder and lead designer at 3D Cakes, said:
"We love a challenge at 3D cakes so when we were given the brief to create the 8ft replica ship we knew that it would be hard but also something that we would never forget".
David and his team were helped by two Navy chefs, Jessica Mycroft and Aaron Wright from HMS Queen Elizabeth, who helped to make sure the look and the feel of the cake were exactly right.
Warrant Officer 1st Class William Shepherd, at Royal Navy, said:
"What they have managed to create is outstanding; a real work of art. I've been in the Royal Navy 28 years and I genuinely believe this is the best commissioning cake I've ever seen. It's definitely representative of the ship and all of its elements."
