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 ↓

Beat the yolks of 2 eggs with the sugar and flour.
Add the vinegar and water, then cook in a double boiler, stirring until thick.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the filling as they cook, and whites whip into the meringue topping.
- Flour
- Starch thickens the filling so it sets firm when cooled.
- Sugar
- Sweetens the filling and balances the sharp taste of the vinegar.
- Vinegar
- Adds acidity and a tangy flavor that defines the pie.
The step that matters
Cooking the filling until thick. Egg yolks and flour thicken as they heat, but overheating can curdle the yolks. Gentle double-boiler heat with constant stirring keeps the custard smooth and sets it properly.
