Hay-Smoked Apple Tarte Tatin

DAY 1 — INVERTED PUFF PASTRY

1. MAKE THE DETREMPE (base dough): Rub the 45g melted butter into the 225g plain flour and 6g sea salt. Add the 120ml cold water and 5ml white wine vinegar; bring together into a smooth rectangular dough. Wrap and rest in the fridge for 1 hour.

2. MAKE THE BUTTER BLOCK: In a stand mixer with the paddle, beat the 450g cold butter with 100g plain flour until pliable and homogenous. Shape into a rectangle roughly twice the size of the détrempe, wrap, and chill 30 minutes.

3. INVERSION AND TURNS: Roll the butter block large, place the détrempe in the centre, and fold the butter block around the dough - the butter encases the dough, not the other way round. Give one double turn (book fold), wrap, and rest 1 hour. Give a second double turn, wrap, rest 1 hour. Give a final single turn, wrap tightly, and rest overnight.

DAY 2 — COMPONENT PREPARATION

4. COLD-SMOKE THE BRAEBURNS: Peel 6 medium Braeburn apples and core neatly, leaving them whole or halved depending on your mould size. Cold-smoke over food-grade hay for 20–30 minutes - a gentle aromatic lift, not a kipper. Set aside.

5. HAY-BAKED APPLE PUREE: Heat the oven to 170°C / 340°F. Lay a generous bed of hay on a small tray, sit the 2 unpeeled Bramleys on top, cover loosely with foil, and bake 45–55 minutes until collapsing. Discard the hay. Pass the baked apples (skins included) through a fine sieve. In a dry pan, bring 100g caster sugar and 30ml water to a mid-amber caramel. Deglaze with the apple pulp, whisk until smooth, and reduce to a slow-dropping purée. Stir in 5ml apple cider vinegar and a pinch of salt. Cool.

6. HAY ICE CREAM: Toast 25g hay in a dry pan for 60–90 seconds until it smells like warm bread crust. Scald with the 480ml whole milk and 180ml double cream; cover and infuse 30 minutes off the heat. Strain and discard the hay. Whisk the 6 egg yolks, 130g caster sugar, 20g glucose syrup and a pinch of salt; pour on the warm milk; return to a clean pan and cook to 82°C / 180°F, stirring constantly, until the custard coats the spoon. Strain into a bowl set over ice. Chill, churn, and freeze.

7. HAY BROWN BUTTER (for the sablée): In a small pan, cook the 170g unsalted butter to a deep hazelnut brown, foaming past the golden stage until the milk solids at the bottom are toffee-coloured. Off the heat, add 15g toasted hay; cover and infuse 20 minutes. Strain through muslin, discard the hay, pour into a shallow tray and chill until firm.

8. FROZEN SABLEE: In a stand mixer with the paddle, cream the chilled hay brown butter with 85g icing sugar and 3g fine sea salt until smooth. Add the 2 egg yolks one at a time. Tip in 170g plain flour and mix only until it just comes together. Roll between two sheets of parchment to about 4mm thick and freeze flat — this is a frozen sablée, never baked. Freeze solid for at least 3 hours; overnight is better.

9. TATIN CARAMELS: In a heavy-based pan, combine 250g caster sugar and 60ml water. Do not stir once it comes up to the boil. Cook to a mid-to-dark amber, swirling the pan. Off the heat, whisk in the 55g cold cubed butter. Divide the caramel immediately between six buttered individual tatin moulds, tilting each to coat. Let set.

10. ASSEMBLE THE TATINS: Sit a smoked, peeled Braeburn (or two halves, cut-side up) into each caramel-lined mould. Roll the rested inverted puff pastry to 3mm thick. Cut six discs slightly larger than your moulds and tuck the pastry snugly around the apples - this becomes the base when inverted. Prick lightly. Chill 20 minutes.

11. BAKE THE TATINS: Bake at 200°C / 400°F for 22–28 minutes, until the pastry is puffed, dark golden, and lacquered underneath by bubbling caramel. Rest 5 minutes before turning out onto warm plates - pastry side down, burnished apple top up. The caramel needs a moment to thicken or it will flood the plate.

12. REDUCED APPLE JUICE GLAZE: While the tatins bake, reduce the 475ml apple juice in a wide pan with a pinch of sea salt flakes over medium heat to a glossy, dark, syrupy reduction - about 80% evaporation. Off the heat, stir in 10ml apple cider vinegar. Brush the hot tatins with this glaze the moment they are turned out.

13. CIDER BRANDY CREAM: Chill the mixing bowl and whisk. Combine the 240ml very cold cream, 15g icing sugar and 30ml Somerset cider brandy. Whip on medium speed to less than soft peaks - stop the moment the whisk leaves a trail.

14. PLATE THE 'APPLE GARDEN': On each second plate, dot three small spoonfuls of the hay-baked apple purée. Scatter seven or eight russet apple pearls (cut with a 7mm parisian scoop from the 1 large russet). Tuck in five blanched hazelnut halves. Lay three or four long shards of frozen sablée, shaved from the frozen sheet with a microplane in single sweeps - long curls, like strands of hay. Top with a quenelle of hay ice cream and dust with toasted hay powder. Sprinkle the cider brandy cream with meadowsweet pollen. Serve the glazed tatin alongside, and a small jug of cider brandy cream.

CHEF'S NOTES:
• Inverted puff is the whole game - it shatters rather than flakes, a deliberate lamination choice that suits caramel saturation.
• Smoke gently. Measured in minutes, not hours. If the smoke is unmistakable, you have gone too far.
• The russet is the acid spine, not a flourish. A tatin of this richness reads slack without raw fruit.
• Frozen sablée is mechanically simple; the secret is a deep, deep freeze.
• Do not over-whip the chantilly - alcohol destabilises fat emulsion faster than plain cream. Target less-than-soft peaks.
• Meadowsweet pollen substitutes: a light dust of dried chamomile flower or bee pollen gives the same floral high note.

TROUBLESHOOTING:
• Heavy, tight pastry — butter block was too warm during turns, or rests were too short. Chill 45+ minutes between every fold; if the butter starts to show through the dough, stop and chill, do not press on.
• Caramel seizes in the moulds - butter whisked in too late, or moulds too cold. Warm moulds briefly in a low oven before pouring; divide while still mid-amber and hot.
• Watery, poached-looking tatin apples - pre-smoke gently to dehydrate the surface, and bake at a true 200°C with an oven thermometer; tatins cannot be rushed at lower temperatures.
• Sablée crumbles instead of shaving into curls - not frozen solid enough. Freeze 3+ hours, ideally overnight. Shave with a single smooth pull of the microplane.
• Grassy or sour ice cream - hay was infused too long, or hot-infused. Toast briefly, scald milk, then steep 30 minutes off the heat. Strain promptly.
• Grainy cider brandy cream - whipped past soft peaks. Stop when the whisk leaves a trail; if it breaks, fold in 1–2 tbsp unwhipped cream to recover.

STORAGE & MAKE-AHEAD:
• Inverted puff pastry: up to 3 days in the fridge (improves with rest), or freeze 1 month after the final turn.
• Hay-baked apple purée: 3 days in the fridge in an airtight container.
• Hay ice cream: best within 48 hours.
• Frozen sablée: up to 2 weeks wrapped tightly in the freezer. Shave fresh at service.
• Unbaked assembled tatins: hold up to 8 hours in the fridge; brush the top with melted butter so the pastry does not dry.
• Cider brandy cream: whip fresh for service.
• Baked tatin: best within 15 minutes of turning out.

VARIATIONS:
• All-butter shop-bought puff: loses about 15% of the dish's character but remains excellent.
• Pear tatin: substitute firm-ripe Comice pears for the Braeburns; reduce bake time by 3–4 minutes.
• Calvados in place of cider brandy: a straight swap.
• Chamomile or lemon-balm purée: if sourcing food-grade hay is impossible, chamomile steeped like tea and folded into apple purée gives a meadow-adjacent lift.
