Why it works: Sugar and syrup match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Lemon Syrup Tart
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the pastry
Preheat the oven to 400°F (200°C).
In a bowl, mix the flour, sugar, baking powder, and salt.
Rub the lard or dripping into the dry ingredients until crumbly.
Add enough cold water to form a firm paste.
Roll out the pastry and line a greased tart tin with it.
Fill and bake
In another bowl, mix the bread crumbs, lemon juice, and syrup.
Spread the mixture over the pastry.
Lay strips of pastry in a lattice pattern on top.
Bake for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the pastry's structure when bound with water and fat.
- Lard
- Fat that shortens the pastry, keeping it tender and crumbly.
- Baking powder
- Releases gas in the dough to lift and lighten the pastry.
- Lemon juice
- Adds acidity that brightens the sweet syrup filling.
- Lyle's golden syrup
- Provides sweetness and a moist, sticky body to the filling.
- Bread crumbs
- Absorb liquid and help the syrup-lemon filling set.
The step that matters
Add enough cold water to form a firm paste. Too little water leaves the pastry crumbly and hard to roll, while too much makes it tough, because gluten develops with more liquid and more working. Keeping the water cold helps keep the fat solid so the pastry stays flaky.

Fit is the average pairing score against flour, sugar, bread, syrup. Candidates are from the same food group and used in at least 100 recipes.
