Billie wrangling the sugar ball.

With 120 ingredients and 66 steps, Heston Blumenthal’s ‘Botrytis Cinerea’ isn’t just a dessert – it’s a scientific experiment.

Judge Gary Mehigan called Blumenthal’s masterpiece “the toughest dish ever”, with even Blumenthal himself admitting it had broken seasoned chefs before.

“To get it right, it normally takes about two months,” the chef admitted.

MasterChef winner Billie McKay managed to complete the mammoth task in just five hours, with only a couple of missteps along the way.

In particular, the 24-year-old struggled to craft a perfect “sugar ball”, breaking down in tears as she pumped air into a fragile golden clump under a heat lamp.

“That sugar ball was just about as frustrating to watch as it was to make!” McKay told The New Daily of re-watching the tense moment on Monday night.

“Especially as I’m heading over to the UK to join’s Heston’s team I’d love to give it another go. Maybe it won’t take me five hours second time around?!”

The restaurant manager from Bowraville said she’s preparing to make the move to Bray with her boyfriend Hadyn in a couple of months to take up Blumenthal’s coveted job offer.

In the meantime, you can put your own culinary skills to the test by recreating the Botrytis Cinerea in your own kitchen.

Here’s the 2800-word recipe. You’re going to need trehalose. Yeah – we’re not sure what that is either.

Citrus Reduction

1. Place all ingredients in a saucepan and set over high heat. Whisk together and allow to boil until reduced by half. Set aside.

Citrus Sorbet

1. Place all the citrus segments in a thermomix and process at maximum speed for 3 minutes to make juice. Pass through a fine chinois.

Remove from heat, add another 100 grams juice and stir to combine. Cool mixture over an ice bath. Add vodka and yoghurt to the cooled mixture and whisk to combine. Transfer mixture to an ice cream machine and churn the mixture until frozen. Set aside in freezer.

Frozen Grapes

Transfer to a piping bag and set aside in the fridge.

Billie serves up the finished product.

Grapeseed Oil Crumble

1. Place the flour, corn flour and icing sugar in a bowl and mix together. Add grapeseed oil and melted butter to the mixture and make a crumble like texture. Transfer to a tray and place in the 120C oven to bake for 1 hour. Remove from oven and set aside.

Churros Stalks

1. Place the water, oil, sugar and salt in a pan. Bring it to a boil, immediately take off the heat, sieve the flour in, in 3 batches, mixing well after each addition. Transfer to a piping bag (2mm hole). Allow to cool until cool enough to handle.
2. Lay stalk guide sheet on a baking tray and cover with a sheet of baking paper. Pipe the dough onto baking paper, following the stalk shape and pressing joins together. Place in 180C oven to cook for 2 minutes. Brush grapeseed oil on the dough, making sure to completely cover. Continue to cook, turning the tray, as necessary, until an even golden colour, about 12 more minutes. Remove from oven.

Crystallised Chocolate

1. Place the water and sugar in a pan and heat to 150C. Meanwhile, melt both chocolates and mix. Gradually add the melted chocolate mixture into the sugar syrup and using a whisk stir well. Transfer to a paper lined tray and set aside to cool.

Roquefort Powder

1. Place chocolate and roquefort cheese in a bowl and place over a pot of gently simmering water to melt, stirring frequently. Place tapioca malto dextrin in a bowl. Slowly pour melted chocolate mixture into the malto dextrin, while constantly whisking, until well combined and a powder forms. Set 10 grams aside for making soil and remaining aside for plating.

Vanilla Salt

1. Place scraped vanilla bean in the dehydrator for 24 hours. Transfer to a spice grinder and grind until smooth. Add salt and grind just until combined. Set aside.

Soil

1. Mix all of the ingredients together to make a fine crumble and set aside in an airtight container.

Citrus Cream

1. Place yogurt in a muslin lined sieve and place over a bowl. Allow to stand at least 2 hours to separate. Discard whey.
2. Place 200g hung yogurt, citrus reduction, icing sugar and orange blossom water in a bowl and stir to combine. Set aside in the fridge.

Chocolate Balls

1. Place cocoa butter in a plastic bowl and melt, using bursts in the microwave. Add the green, yellow and red colouring and stir to combine. Add 350 grams white chocolate and place in the microwave in bursts, stirring each time, until chocolate has melted. Add remaining 150 grams chocolate, a little at a time, while constantly stirring until completely incorporated and temperature reaches 30 C.
2. Pour tempered chocolate over half sphere mould. Move mould around to coat and tap to remove air bubbles. Tip out excess chocolate and wipe off excess chocolate from top of mould. Place in the freezer.
3. Meanwhile, mix feulletine and popping candy together. Remove chocolate half spheres from the freezer and unmould. Fill a half sphere with the feulletine mixture. Warm a baking tray and hold another empty half sphere onto it, just to warm. Stick the warmed half sphere and the filled half sphere together, rubbing seam gently to remove, to form a ball.
4. Combine kirsch and red colouring to make red spray. Transfer to a small spray bottle and spray the ball very lightly from a distance, and set aside in an airtight container.

Apricot Filled Grape

1. Place apricot puree and glucose in a saucepan and set over medium heat. Mix sugar and pectin and add to saucepan and continue heating to 107C. Remove from heat, add Amaretto and pour into a tray and place in the fridge until set.
2. Transfer set apricot gel to the thermomix and process until smooth. Transfer to a piping bag.
3. Meanwhile, open dried grapes and remove seeds. Pipe some apricot puree into the dried grapes and set aside.

Leaf – Green Grape Paste

1. Blitz grapes in thermomix for 30 seconds. Strain through a fine chinois.
2. Blitz isomalt in thermomix to a fine powder. Add 100 grams of strained grape juice and remaining ingredients and blitz to 100C. Set aside

Leaf – Purple Grape Paste

1. Blitz grapes in thermomix for 30 seconds. Strain through a fine chinois.
2. Blitz isomalt in thermomix to a fine powder. Add 100 grams of strained grape juice and remaining ingredients and blitz to 100C. Set aside

Leaf

1. Using a leaf stencil, spread the green leaf paste onto a silpat mat and dry at 70C in the dehydrator for 3 hours.
2. Brush purple grape paste on the half dried green leaf and return to the dehydrator for 48 hours.
3. To make the leaf, place grape paste leaf onto the indented side of the leaf stamp and hold under the sugar lamp to warm. Press other side of leaf stamp on top of leaf to shape leaf. Repeat to give one big and one small leaf. Set leaves aside in an airtight container.

Grape Sugar Bubble and Spiral

1. Place water, glucose and isomalt in a saucepan and set over medium heat. Cook to 140C, add citric acid, kirsch and colouring and whisk to combine. Continue heating to 165C. Remove from heat and pour into a silpat lined tray.
2. Once cool enough to handle, put on 2 pairs latex gloves, followed by safety gloves covered with another pair latex gloves. Wear safety goggles.
3. Work sugar by continually pulling, folding over and pressing sugar until it is an even golden colour and very shiny. Re-warm sugar in 5 second bursts in the microwave if it becomes too cold to work with.
4. To make the spiral, re-warm and pull sugar as necessary to become golden and shiny once more. Working under the heat lamp pull a little sugar away from the lump and twist around a wooden dowel a couple of times to create a spiral. Let spiral set for a second then slide off dowel. Twist and shape spiral, break off from the sugar lump, leaving a straight piece at the end of the spiral and give a final twist so that the spiral will stand straight. Set spiral aside in an airtight container.
5. To make the sugar bubble, place sugar under the lamp to keep warm. It will turn a little brown as it cools. Pull a 4-5 gram piece from the lump and cut it off with scissors. Rework piece by pulling and folding until it becomes really shiny once again. Shape into a flat, square shape.
6. Heat the copper rod of the sugar pump with a blow torch until too hot to touch. Fold the sugar piece over the end of the pump, leaving a gap between the piece and the end of the pump. The piece should stick to the pump. If it does not stick the pump end is too cold and needs further heating. Press the piece around its base to seal onto the pump end forming a ball.
7. Using one hand gently press pump to inflate ball while at the same time slowly spin the pump end with the other hand and press up from the base of the ball with the thumb to create a perfect sphere. Heat a knife with a blow torch and use hot knife to cut ball from pump end. Set ball aside in an airtight container.
