Classic Treacle Tart with Shortcrust Pastry

A Proper British Teatime Classic

Few bakes say "teatime" quite like a treacle tart. The filling is little more than golden syrup, fresh breadcrumbs and lemon, yet it bakes into something deep, chewy and almost caramel-like, with the sharpness of the lemon cutting cleanly through the sweetness. It is also cheap, quick to put together and forgiving — the sort of pudding you can make on a grey Sunday afternoon and still be eating warm two hours later.

One word on the name: despite the title, a traditional treacle tart is made with golden syrup, not the dark, bitter black treacle. A single spoonful of black treacle stirred in with the syrup adds depth, but any more will swamp the lemon and turn the filling heavy. This version sits in a crisp shortcrust case under a lattice lid, which lets steam escape and gives you crisp pastry against every spoonful of soft filling.

What You'll Need

This makes a 23cm tart that serves eight generously. You will also want a fluted loose-bottomed tart tin, baking beans or dried rice, cling film and a pastry brush.

For the pastry

• 200g plain flour
• 100g cold unsalted butter, cut into 1cm cubes
• 1 tbsp icing sugar
• A good pinch of fine salt
• 1 egg yolk
• 1–2 tbsp ice-cold water

For the filling

• 400g golden syrup
• 1 tbsp black treacle (optional)
• 130g fresh white breadcrumbs
• Zest and juice of one unwaxed lemon
• 1 large egg plus 1 extra yolk
• 2 tbsp double cream
• Half a teaspoon of ground ginger (optional)

Shortcrust Pastry, Done Properly

Tip the flour, icing sugar and salt into a large bowl. Add the butter and rub it in with your fingertips until the mixture looks like coarse breadcrumbs with a few larger flakes still visible — those flakes are what make shortcrust short, so stop before it turns to sand. Add the egg yolk and one tablespoon of iced water, then bring everything together with a round-bladed knife and finally your hands, adding the second spoonful of water only if the dough refuses to come together.

Flatten into a disc, wrap in cling film and chill for 30 minutes at least. Roll out on a lightly floured surface to about 3mm thick, line the tin, and press the pastry gently into the fluted edges without stretching it. Trim, leaving a 2cm overhang, prick the base all over with a fork and chill again for 15 minutes.

Heat the oven to 200°C (180°C fan, gas 6). Line the case with baking paper and fill with beans, bake for 20 minutes, then remove the paper and beans and bake for a further 4–5 minutes until the base is a pale biscuit colour. This is the step that keeps the pastry crisp under a wet filling.

The Golden Syrup and Breadcrumb Filling

Warm the golden syrup, and the black treacle if using, in a small pan over a low heat until it is runny. Do not let it simmer, or it will reduce and set rock-hard once baked. Take it off the heat.

In a bowl, rub the lemon zest into the breadcrumbs with your fingertips, then stir in the egg, yolk, cream, ginger and a pinch of salt. Pour in the warm syrup and the lemon juice and mix thoroughly. Let it stand for 10 minutes so the crumbs drink up the syrup; the filling should be slack but not watery.

Fresh breadcrumbs genuinely matter here. Dried ones give a gritty, sawdusty texture, so blitz two-day-old white bread in a processor until coarse. The crumb should still have some bite.

Lattice Top and Baking

Roll the pastry trimmings into a thin rectangle and cut into strips about 1.5cm wide. Spoon the filling into the chilled case and level it. Lay half the strips across in one direction, then weave the second set over and under to form a lattice, pressing the ends onto the pastry rim and trimming neatly. If weaving feels fussy, lay every strip the same way for a simple trellis — it bakes just as well and looks pleasingly rustic.

Brush the pastry with beaten egg and scatter over a little demerara sugar for crunch. Reduce the oven to 180°C (160°C fan, gas 4) and bake for 25–30 minutes, until the lattice is deep gold and the filling is set at the edges with only a faint wobble in the centre. Cover loosely with foil if the pastry browns too quickly.

Serving, Storing and Troubleshooting

Rest the tart in its tin for at least 30 minutes before releasing it — the filling firms as it cools and will flood the plate if you cut it hot. Serve warm, not scalding, with clotted cream, pouring cream, custard or vanilla ice cream.

Leftovers keep covered at room temperature for two days, or in the fridge for four. Warm slices through at 160°C (140°C fan, gas 3) for ten minutes. If the pastry shrank in the tin, it was stretched during lining rather than eased into the corners. If the filling still seems loose once cool, it needed a few more minutes in the oven. And if it bubbles over the rim during baking, you filled it a little too generously — set the tin on a baking tray next time.
