Why it works: Syrup and lemon are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 2,235 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Treacle Tart
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the filling
In a bowl, combine the golden syrup, breadcrumbs, grated lemon rind, and lemon juice. Mix well.
Assemble and bake
Line the tins with short paste.
Spoon about 1 tablespoon of the mixture into each tin.
Bake in the preheated oven until set.

Shared aroma: ethanol (alcoholic, ethereal).
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Golden syrup
- Provides the sweetness and the sticky, rich body of the filling.
- Breadcrumbs
- Absorb the syrup and help thicken the filling as it sets.
- Lemon juice
- Adds acidity that cuts the sweetness of the syrup.
- Lemon rind
- Adds aromatic oils that give a bright lemon fragrance.
The step that matters
Baking until set. Golden syrup is very sugary and the filling thickens as it cools, so underbaking leaves it runny while overbaking can make it dark and hard. Check that the centre is firm to the touch before removing the tarts.
