The winner of the Platinum Pudding competition has been pictured celebrating in Fortnum and Mason after taking home the top prize.
Jemma Melvin said the experience had been “surreal” after only deciding to enter after a friend suggested it to her.
Her trifle, made with lemon Swiss roll and amaretti, beat 5,000 desserts to become the official pudding of the Queen’s Jubilee celebrations.
The dish, inspired by her grandparents, is set to follow in the footsteps of coronation chicken and Victoria sponge as it becomes part of Britsh royal food history.
Ms Melvin, a copywriter from Southport, Merseyside, has been pictured celebrating winning the top prize in Fortnum and Mason among a crowd of adoring spectators.
Following her victory, she said: “It was my friend Sammy who actually sent me the link to apply for the competition and I just thought I might as well go for it, get my name in the hat.
“I didn’t think I’d go any further but I made it to the final 50, made it to the final five, and now my pudding has been chosen. It’s ridiculous.”
Speaking about the inspiration behind her winning trifle, Ms Melvin explained: “This particular trifle is a tribute to three women: it’s my Gran, my Nan and the Queen herself.”
She added: “My Grandma taught me to bake, she taught me all the elements, everything from scratch.
“My Nan’s signature dish was always a trifle; we used to call her the queen of trifles. And the Queen had lemon posset at her wedding.”
The trifle has lemon curd Swiss roll on the bottom, St Clement’s jelly, lemon custard, amaretti biscuits, mandarin coulis, whipped cream, candied peel, chocolate shards and crushed amaretti biscuits.
It was crowned on BBC One’s The Jubilee Pudding: 70 Years In The Baking by the judges who included Dame Mary Berry and Monica Galetti.
She saw off competition from four other bakers whose creations included a passionfruit and thyme frangipane tart, a Jubilee Bundt cake featuring home-made Dubonnet jam, a rose falooda cake and a “four nations” pudding featuring ingredients from around the country.
Ms Melvin said she hopes her winning recipe will be made by bakers across the UK to celebrate the Queen’s 70 years on the throne.
“I’m hoping that everyone across the country is going to make this, I’ve made it really accessible,” she said.
Royal grocer Fortnum and Mason joined forces with the Big Jubilee Lunch Charity to challenge members of the British public to create an original and celebratory cake, tart or pudding.
It had to fulfil the criteria of being fit for a queen, having a memorable story and being achievable for home bakers, as well as tasting good.
Emotional Ms Melvin broke down in tears when Dame Mary, who chaired the competition’s judging panel, told her she had “nailed” the brief.
She said: “She was lovely but she was also a very serious judge and I appreciated that because it was great to get her advice and her feedback. She actually made me cry with her feedback because it was so lovely.”
Ms Melvin added: “She said I nailed it. And from Mary Berry saying that I’ve nailed a recipe and a bake to a brief that she knows everything about, that was it, that was the moment.”
The Duchess of Cornwall joined Dame Mary to praise Ms Melvin wishing her “many congratulations”.
“She was a warm and wonderful woman,” said Ms Melvin.
Speaking about the winning dish, Dame Mary said: “It’s absolutely wonderful; I think Britain is going to be so delighted and the Queen too.”
