Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Thickens the sauce as it cooks, giving it body.
Butter
Adds richness and smoothness to the sauce.
Sugar
Provides sweetness that balances the tart lemon.
Lemon juice
Adds acidity and bright lemon flavour.
Egg
Enriches the sauce and helps it set slightly when stirred in.

The step that matters

Boil the mixture until it thickens. Flour only thickens fully once it has boiled, as its starch swells in hot liquid. Reducing the heat afterward and cooking a little longer removes the raw starch taste and keeps the sauce from scorching.

Swap the lemon

How well each one fits the dish's main ingredients (flour, butter, sugar, egg):

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