Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Provides sweetness that balances the sharp vinegar and lemon.
- Vinegar
- Adds the tart, acidic flavor that defines this pie.
- Flour
- Thickens the liquid filling as it heats so it sets rather than staying watery.
- Pie crusts
- Encase the filling and form the golden, browned top and base.
The step that matters
Bring the mixture to a boil. Flour must be heated fully to gelatinize its starch; otherwise the filling stays thin and tastes raw-floury. Boiling also thickens the filling before it goes into the crust.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, vinegar, flour):

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