Tarte au Citron
- Advanced
- 2 h 30 m
- roughly 2 of 4 for cost
- Vegetarian
Leads with richness that coats and comforts, acid holding everything up to the light, on a slow, honest burn.
Ingredients
- Pâte sucrée: 250g flour, 100g icing sugar, 125g cold butter, 1 egg, pinch salt; blind-baked to full biscuit gold
- The cream: zest of 3 lemons rubbed into 180g sugar (the perfume step), 160ml lemon juice, 4 eggs + 2 yolks
- 200g butter, cubed, whisked in off the heat: the French curd method; silk is the target
- Optional crown: nothing (Paris), or Italian meringue torched (the tarte au citron meringuée faction)
- A 24cm tart ring; a microplane; conviction about sourness

Method
- Rub zest into sugar until it looks like wet sand and smells like a grove; whisk with juice, eggs and yolks.
- Cook over a bain-marie, whisking, to 82°C: thick ribbons, spoon-coating; strain immediately.
- Whisk in the cold butter piece by piece off the heat until the curd turns to lemon silk; pour into the fully baked shell.
- Bake 130°C just 8–10 min to set the surface (or simply chill 4 h for the no-bake-set school). The top should be mirror-flat. Slice with a hot knife; the cut face should stand glossy and clean. 10 min
How it should come out
- The surface is mirror-flat and one even deep yellow: no bubbles risen through it, no crazed or wrinkled skin, no browned rim where the curd met the pastry.
- Lift a slice on the knife: the base carries its own weight without drooping, and the underside is an even biscuit brown right to the centre with no pale, damp patch.
- A hot knife leaves a clean vertical cut face, glossy and square, and it has not crept or slumped after five minutes on the plate.
- The curd is silk on the tongue (no grain, no thread of cooked egg, no specks of zest caught in it), and the cut face is glossy rather than dull and matte.
- Sour arrives before sweet and the swallow makes the mouth water. If the sugar lands first, it does not go out.
Where it goes wrong The curd is pushed past 82°C, or cooked over direct heat instead of the bain-marie: it scrambles at the pan wall, and even strained it sets dull and grainy and weeps a thin syrup onto the surface overnight.

Citrus desserts need a wine sweeter than they are, with acid enough to keep up: light, frothy, and low-proof wins.
