Winning Platinum Pudding recipe - how to make perfect lemon and amaretti trifle

A lemon swiss roll and amaretti trifle has made history, after it was awarded the title of "Platinum Pudding" for the Queen's Jubilee celebrations.

Jemma Melvin, a copywriter from Southport, beat more than 5,000 entries with her recipe now following in the footsteps of 1953's coronation chicken to honour the 96-year-old monarch.

In preparation for the Queen's Platinum Jubilee, Fortnum & Mason challenged the UK earlier this year to rustle up a dessert "for a Queen", with it needing to include a memorable story, taste great and be simple enough for home bakers to do at home.

Speaking of her win, Ms Melvin said: "I wanted it to be the People's Pudding, not just for the Queen, but the whole of the country."

Judged by a panel including Dame Mary Berry, chef Monica Galetti and former The Great British Bake Off winner Rahul Mandal, their decision was unanimous.

So, if you want to celebrate the Queen's 70-year reign by creating the trifle at home, Ms Melvin's Jubilee Pudding recipe has already been released.

hat you will need

Two Swiss roll tins, measuring approximately 24cm x 34cm, and a trifle dish with capacity of approximately 3.5 litres/6 pints. However, you can always halve the recipe to serve 10.

The ingredient list is rather large, but feel free to buy shop-bought Swiss rolls, lemon curd, custard and amaretti biscuits instead.

This is the official Jubilee Pudding recipe used by Ms Melvin and released on the BBC's Good Food website.
• To make the Swiss rolls, preheat the oven to 180C/160C Fan/Gas 4. Grease and line the two Swiss roll tins with baking paper. In a large bowl, beat the egg and sugar together with an electric hand whisk for approximately five minutes or until light and pale. Using a metal spoon, gently fold in the flour. Divide between the two tins and bake for 10–12 minutes, or until the sponges are lightly golden and cooked through.
• Sprinkle some extra caster sugar on two sheets of baking paper then turn the sponges out onto the sugared paper. Peel off the paper from the underside and, while still warm, roll them both up from the short end into a tight spiral using the paper to help. Leave to cool.

• To make the lemon curd, place the egg yolks, granulated sugar, butter, lemon zest and lemon juice in a glass bowl over a saucepan of simmering water (don't let the bowl touch the water). Whisk until combined and whisk continuously as the curd cooks until thickened. This should take about 15 minutes. Pour into a clean bowl and set aside to cool.
• To make the St Clement's jelly, soak the gelatine leaves in cold water for 5 minutes to soften. Using a vegetable peeler, peel 6 strips from a lemon and 6 strips from an orange and put these into a saucepan with the sugar and 400ml water. Bring to a simmer over a medium heat, stirring occasionally until the sugar has dissolved. Remove from the heat and discard the peel.
• Squeeze the water out of the gelatine and stir into the pan until dissolved then leave to cool. Squeeze the lemons and oranges, so you have 150ml of both lemon and orange juice. Stir into the pan then strain the jelly through a fine sieve into a jug and chill until cool but not set.
• To make the custard, place the cream in a saucepan over a gentle heat and bring it up to simmer, stirring occasionally with a wooden spoon. In a bowl, whisk together the egg yolks, sugar, cornflour and lemon extract, then gradually pour the hot cream into the bowl while whisking continuously. Immediately return the whole lot back to the saucepan and continue whisking over a gentle heat until the custard is thick and smooth. Pour the custard into a jug or bowl, cover the surface with greaseproof paper and leave to cool.
• To make the amaretti biscuits, preheat the oven to 180C/160C Fan/Gas 4. In a large bowl, beat the egg whites until firm. Mix the sugar and almonds gently into it. Add the amaretto and fold in gently until you have a smooth paste.
• Place some baking paper on a baking tray and lightly brush with butter or oil. Using a teaspoon, place small heaps of the mixture approximately 2cm apart, as they will expand during cooking. Bake for approximately 15–20 minutes or until golden brown. Remove from the oven and set aside to cool.
• To make the chunky mandarin coulis, strain two tins of mandarins. Discard the juice and put the fruit into a saucepan with the sugar and heat gently until broken down. Remove from the heat. In a small bowl, slake the arrowroot with two tablespoons cold water then add to the warm mandarins. Add the lemon juice and mix well before pouring into a large bowl. Strain the remaining two tins of mandarins and add the fruit to the bowl then leave to cool completely.

• To make the jewelled chocolate bark, if the peel feels wet or sticky, roll in the caster sugar to absorb any moisture. Melt the white chocolate in a bowl sitting over a saucepan of gently simmering water. Pour the white chocolate onto a baking tray lined with baking paper and scatter over the mixed peel. Leave to set then break into shards.
• To assemble, unroll the cooled Swiss rolls and spread with the lemon curd. Roll back up again and slice one into 2.5cm slices and place upright around the bottom edge of the trifle dish so the swirl is visible. Slice the other Swiss roll into thicker pieces and use these to fill the bottom of the dish, ensuring the top is roughly the same level as the slices that line the edge. Use off-cuts of sponge to fill any gaps.
• Pour the St Clement's jelly over the Swiss roll layer and set aside in the fridge to completely set. This will take approximately 3 hours. Once set, pour over the custard then arrange a single layer of amaretti biscuits, keeping a few back for the top. Pour over the mandarin coulis. In a large bowl, whip the double cream until soft peaks form then spoon this over the coulis. Crumble over the reserved amaretti biscuits and decorate with the chocolate bark shards.
