Treacle Tart

the English tart built from a refinery by-product: golden syrup warmed with lemon and stirred into fresh breadcrumbs, poured into a shortcrust case, and baked until it sets to a chewy amber

Origin: England

From the journey of Sugar Cane.

The treacle tart is younger than it tastes. It could not exist before 1885, when Abram Lyle's refinery on the Thames at Plaistow began selling the pale invert syrup left over from sugar refining as Lyle's Golden Syrup, in the green and gold tin with the dead lion and the line from Judges upon it that has scarcely changed since. Before that, English 'treacle' meant the dark bitter molasses that is now sold as black treacle, and before that it meant a medicinal compound entirely, from the Greek thēriakē, an antidote to venom. What Lyle produced was cheap, mild, and universally available, and English cooks put it into everything: parkin, flapjack, gingerbread, treacle sponge, and this tart, which is nothing but syrup, breadcrumbs, and lemon in a pastry case and is one of the best things in the entire British repertoire. The breadcrumbs are not padding but structure; they absorb the syrup and hold it in a chewy, dense, faintly grainy set that a custard cannot imitate. It is the pudding of the school dining hall and the country pub, of Sunday lunch and of Harry Potter, and its whole existence traces back to a Scottish sugar refiner finding a use for something his competitors were throwing away.

Ingredients

Pastry

200 g plain flour
100 g cold unsalted butter, cubed
30 g icing sugar
1 whole egg yolk
2 tbsp very cold water
1 pinch fine salt

Filling

450 g golden syrup
2 tbsp black treacle
150 g fresh white breadcrumbs (from a day-old loaf, crusts removed)
2 whole lemons, zest finely grated and 3 tbsp juice
1 whole egg, lightly beaten
60 ml double cream
0.5 tsp ground ginger (optional)

Method

Rub the butter into the flour, icing sugar, and salt to fine crumbs, then bind with the egg yolk and just enough cold water to come together. Flatten to a disc, wrap, and chill for 30 minutes.
Roll out and line a 23 cm loose-bottomed tart tin, leaving the excess hanging over the rim. Chill for 15 minutes, then line with parchment and baking beans and blind-bake at 190°C (170°C fan) for 15 minutes. Remove the beans and bake 5 minutes more.
Warm the golden syrup and black treacle together in a pan over a low heat until runny but not hot. Take off the heat and stir in the breadcrumbs, lemon zest, lemon juice, and ginger if using. Leave to stand for 10 minutes.
Beat the egg and cream together and stir into the cooled syrup mixture. Pour into the pastry case and level the surface.
Reduce the oven to 170°C (150°C fan) and bake for 35 to 40 minutes, until the filling is set at the edges and still has a slight wobble at the centre. Cool in the tin for at least an hour before serving warm or at room temperature.

Notes

Golden syrup is a cane-refinery product and there is no true equivalent; American light corn syrup is thinner and much blander, and honey is quite wrong here. If you cannot obtain it, a mixture of four parts light treacle or cane syrup to one of glucose comes closest. The black treacle is optional but it deepens the colour and cuts the sweetness, and the lemon is not optional at all, since without a good deal of acid the tart is cloying. The lattice top seen in many versions is decorative rather than traditional; the plain open tart is the older form. Leftovers keep three days in a tin and are very good cold, and a slice warmed for a few seconds recovers the texture completely.
