Tarte Tatin

Upside-down apple tart. The apples are caramelised in butter and sugar in a pan, topped with pastry, baked, then inverted. It looks dramatic; it is not technically difficult. The risk is the inversion.

Peel, quarter, and core the apples. Toss with a squeeze of lemon juice.

In a 24cm ovenproof frying pan (cast iron is ideal), melt the butter over medium heat. Add the sugar in an even layer. Cook without stirring until it turns a deep amber caramel — about 8–10 minutes. Remove from heat immediately when it reaches a dark golden colour.

Arrange the apple quarters tightly in the caramel, curved-side down. They will shrink during cooking so pack them in. Return to the heat and cook for 10 minutes until the apples are just tender and the caramel is bubbling thickly around them.

Roll the puff pastry to a circle slightly larger than the pan. Lay it over the apples, tucking the edges down around them inside the pan.

Bake at 200°C for 25–30 minutes until the pastry is deep golden and cooked through.

Leave to cool in the pan for 5 minutes. Place a plate larger than the pan firmly over the top and invert in one confident movement. Serve warm with crème fraîche.

Method

Tarte Tatin works by building a caramelisation|caramel bed so deep and flavourful that it holds the apples even when inverted. The inversion itself is the tension — get it wrong and you scrape apple off your table. Get it right and the caramel sets firm enough to act as glue.

Peel, quarter, and core the apples. Squeeze lemon juice over them; the acid slows oxidation and keeps them pale until the heat hits. In a 24 cm ovenproof frying pan — cast iron holds temperature better than stainless steel — melt the butter over medium heat. Once foaming, scatter the sugar in a single even layer. Do not stir. Stir ruins the caramel because sugar crystals catch and seed the batch into grainy sludge. Instead, tilt and swirl the pan as the sugar begins to turn colour. Watch it shift from pale amber to deep mahogany. The moment it reaches that dark mahogany — roughly 8–10 minutes — remove from heat. It keeps cooking from residual heat, so stop before you think you should. Dark caramel tastes of bitter chocolate and toasted nuts; too pale and you've wasted the french-cuisine|French principle of building flavour layers.

Arrange the apple quarters curved-side down in the caramel, fitting them snugly as a single layer. They shrink by a third during cooking, so pack them tight now. Return the pan to medium-high heat and cook for 10 minutes. The caramel will bubble thickly around the apples, darkening slightly — this is right. The apples soften and release their juice, which mingles with the caramel into a glossy reduction.

Roll the puff pastry to a circle just larger than the rim. Lay it over the apples and tuck the edges down inside the pan, sealing them against the fruit. Bake at 200°C for 25–30 minutes until the pastry turns deep golden and feels firm to a light tap — it should sound crisp, not hollow.

Cool for exactly 5 minutes. This firms the caramel enough to hold the structure without setting so hard that it shatters. Place a plate larger than the pan over the top, grip both handles firmly, and flip in one confident movement. Leave it there for 10 seconds before lifting the pan away. Serve warm with crème fraîche to cut the sweetness.
