Nikita created this dish for MasterChef UK Professionals Season 18. The 2022 MasterChef: The Professionals champion returned to set the Skills Test benchmark for Week 7, designing a peach baked Alaska that contestants had to replicate in 20 minutes. The dish layers a Génoise sponge soaked with thyme- and vanilla-scented muscat poaching liquor, wine-poached peaches, a quick cheat's ice cream made by blending frozen peaches with restrained cream, and Italian meringue torched to golden perfection. Matt Tebbutt called the torched meringue 'brilliant' and said 'That looks lovely. Very impressed.' Monica praised the 'fresh peaches and then the ice cream still set perfectly in there.' Both contestants struggled with ice cream consistency, and one made the critical error of starting a French meringue instead of the required Italian meringue. This home version preserves every element of Nikita's benchmark while providing the time to execute each component properly.
Chef’s Notes: Lessons from the Skills Test
Temperature Management Is Everything
Nikita’s demonstration was clear about the governing concern: temperature control at every stage. The poached peaches must be cooled rapidly before meeting the ice cream. The ice cream must be frozen hard enough to survive assembly. The Italian meringue must be fully cooled before application. And the entire assembled dome must be frozen solid before torching. At home, without time pressure, each of these stages can be properly completed - this is where the home version has a significant advantage over the 20-minute competition version.
The Cream Restraint Principle
Both Kieran and Patrick added too much cream to their cheat’s ice cream, resulting in a loose consistency that threatened to melt during assembly. Nikita emphasised that the frozen peaches themselves carry flavour and texture - the cream is just a binder to help the processor work smoothly. Think of it as adding just enough to facilitate blending, not as a major ingredient. The result should tast overwhelmingly of peach, not cream.
Italian vs. French Meringue: A Critical Distinction
Patrick’s critical error was beginning to make a French meringue (whisking raw sugar into egg whites) rather than the Italian meringue Nikita demonstrated. This matters enormously for baked Alaska: French meringue must be baked in the oven to cook the egg whites, which would melt the ice cream. Italian meringue, made with sugar syrup cooked to 118–121°C (244–250°F), effectively pasteurises the egg whites on contact, producing a stable, glossy meringue that only needs torching for colour and warmth. The sugar temperature is non-negotiable - too low and the meringue won’t set properly; too high and you risk scrambling the egg whites.
Assembly at Speed
The competition required everything in 20 minutes, which meant Nikita had to move at pace during her demonstration. At home, you have the luxury of freezing the assembled dome overnight, which makes the final stages (meringue and torching) stress-free. However, the principle remains: once the meringue is on and you begin torching, work quickly. The meringue insulates the ice cream, but it won’t do so indefinitely.
The Poaching Liquor as Flavour Bridge
Nikita’s genius with this dish is the poaching liquor - infused with muscat wine, lemon thyme, and vanilla, then reduced and used to soak the sponge. This means the sponge base carries the same aromatic profile as the poached peaches, creating a unified flavour story from base to dome. Don’t skip the reduction step -
concentrated liquor means concentrated flavour without making the sponge soggy.
Troubleshooting Guide
Ice cream is too soft/melty: The most common problem in the competition. Either the peaches weren’t frozen hard enough, or too much cream was added. Use rock-hard frozen peaches straight from the freezer, add cream sparingly, and refreeze the blended mixture before assembling.
Italian meringue is runny: The sugar syrup didn’t reach 118–121°C. Always use a digital thermometer. Also ensure you continue whisking on high speed until the meringue is completely cool - stopping too early leaves it loose.
Meringue deflates or weeps: The egg whites were overwhisked before adding the syrup, or the syrup was added too quickly. Whites should be at soft peaks (not stiff) when the syrup goes in, and the syrup must be poured in a slow, steady stream.
Sponge is dense or heavy: The egg-sugar mixture wasn’t whisked long enough. Whisk until the batter falls in thick ribbons and triples in volume. Fold the flour gently - overfolding deflates the batter.
Baked Alaska melts when torching: The dome wasn’t frozen solid enough. Freeze for at least 2 hours (overnight is best). Also ensure the meringue is applied in a thick, even layer with no gaps - it’s the insulation that keeps the ice cream frozen.
Peaches taste bland after poaching: The poaching liquor wasn’t reduced enough, or underripe peaches were used. Reduce the syrup by at least half for concentrated flavour. Use fragrant, ripe peaches.
Storage & Make-Ahead Tips
• Sponge: Bake up to 2 days ahead. Wrap tightly in cling film and store at room temperature. Can also be frozen for up to 1 month.
• Poached peaches: Poach up to 2 days ahead. Store in the reduced poaching liquor in the fridge.
• Assembled dome (before meringue): Can be frozen for up to 3 days, well-wrapped. This is the ideal make-ahead stage.
• Italian meringue: Must be made fresh, just before serving. It does not hold well.
• Finished baked Alaska: Serve immediately after torching. This is not a dish that waits.
• Leftover poaching liquor: Makes a gorgeous cocktail ingredient, drizzled over panna cotta, or as a syrup for fruit salad.
Variations & Substitutions
• Individual baked Alaskas: Use small dariole moulds or ramekins for single-serving domes. Reduce freeze time to 1–1.5 hours.
• Nectarine or apricot version: Substitute nectarines or apricots for peaches. Adjust poaching time down slightly for apricots as they’re softer.
• Different wine: Replace muscat with Sauternes, late-harvest Riesling, or even Prosecco for a lighter flavour.
• Herb variations: Nikita used lemon thyme, but basil, verbena, or lavender would complement peach beautifully. Use sparingly.
• Nikita’s Asian twist: True to her style, consider infusing the poaching liquor with lemongrass and a kaffir lime leaf, or adding a pinch of cardamom — reflecting the East-meets-West approach that won her the title.
• No-torch method: If you don’t have a blowtorch, flash the meringue-covered dome under a very hot grill (broiler) for 1–2 minutes, watching constantly. The top will brown in seconds.
Ingredients
Instructions
BAKE THE SPONGE BASE
Preheat oven to 350°F (180°C). Line a 9-inch (23 cm) round cake tin with parchment paper and grease lightly. In a heatproof bowl set over simmering water, whisk the eggs and caster sugar until warm to the touch and the sugar has dissolved. Remove from heat and whisk with an electric mixer on high speed for 5–7 minutes until thick, pale, and tripled in volume — the ribbon stage. Sift the flour over the batter in two additions, folding gently with a large metal spoon. Drizzle the cooled melted butter and vanilla down the side of the bowl and fold in until just incorporated. Pour into the prepared tin and bake for 18–20 minutes until golden, springy to the touch, and a skewer comes out clean. Cool in the tin for 5 minutes, then turn out onto a wire rack. When cool, use the dome mould as a guide to cut a sponge disc that fits snugly as the base.
POACH THE PEACHES
Bring a pan of water to the boil. Score a small cross in the base of each peach and blanch for 30 seconds. Transfer to ice water, then peel. Halve and stone the peaches, then cut into small pieces — Nikita emphasised cutting them small so they cool down quickly. In a saucepan, combine the sugar, water, muscat wine, lemon juice, lemon thyme sprigs, and split vanilla pod with seeds. Bring to a gentle simmer, stirring until the sugar dissolves. Add the peach pieces and poach gently for 5–8 minutes until just tender but holding their shape. Remove the peaches with a slotted spoon and spread on a plate. Get them into the freezer immediately for 10–15 minutes to cool rapidly. Strain and reserve the poaching liquor separately. Reduce the liquor by about half over medium-high heat to concentrate the flavour. Cool completely.
MAKE THE QUICK CHEAT'S PEACH ICE CREAM
Place the frozen peach slices (they must be very hard frozen, straight from the freezer) in a food processor. Pulse until broken into small pieces, then blend, adding cream very sparingly — a tablespoon at a time. The frozen peaches themselves provide the body; too much cream dilutes the peach flavour and softens the frozen consistency. Stop blending as soon as you have a thick, scoopable texture. Add the icing sugar and vanilla and pulse briefly. Transfer immediately to the freezer in a shallow container. The texture should be like firm soft-serve, not liquid. If too soft, freeze for 30–45 minutes before assembling.
ASSEMBLE THE DOME (PRE-FREEZE)
Line the dome mould or bowl with cling film, leaving generous overhang. Spread a thick layer of the cheat's ice cream around the inside of the mould, creating a shell about 1 inch (2.5 cm) thick. Return to the freezer for 15 minutes to firm. Fill the centre with the chilled poached peach pieces. Cover the peaches with more ice cream, pressing gently to eliminate air pockets. Smooth the top flat. Place the sponge disc on top (it will become the bottom when inverted). Brush the sponge generously with the reduced poaching liquor. Press the sponge down gently. Cover with the overhanging cling film and freeze for at least 2 hours, or overnight, until completely solid.
MAKE THE ITALIAN MERINGUE
When ready to serve, make the meringue. Place the egg whites and cream of tartar in the bowl of a stand mixer. In a small saucepan, combine the sugar and water. Bring to the boil over medium-high heat, stirring only until the sugar dissolves, then stop stirring. When the syrup reaches about 230°F (110°C), begin whisking the egg whites on medium speed to soft peaks. When the sugar syrup reaches 244–250°F (118–121°C), immediately remove from heat and, with the mixer running on medium speed, pour the hot syrup in a slow, steady stream down the side of the bowl — not onto the whisk. Increase to high speed and continue whisking for 8–10 minutes until the meringue is thick, glossy, brilliant white, and cool to the touch.
UNMOULD AND COVER WITH MERINGUE
Remove the frozen dome from the freezer. Peel back the cling film and invert onto a serving plate or board. Peel away the remaining cling film. Working quickly, cover the entire dome with a thick, even layer of Italian meringue using an offset spatula or piping bag. Ensure there are no gaps — the meringue acts as insulation, protecting the ice cream from the blowtorch. Create decorative swirls and peaks.
TORCH AND SERVE IMMEDIATELY
Using a kitchen blowtorch, carefully brown the meringue all over, creating an even golden colour with dramatic darker patches at the peaks. Serve immediately — the magic of baked Alaska is the contrast of warm, caramelised meringue and frozen ice cream revealed when you cut through. Slice with a sharp knife dipped in hot water for clean cuts.
