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

What each ingredient does

Cornstarch
Thickens the liquid into a smooth sauce as it heats.
Butter
Adds richness and a glossy finish to the sauce.
Lemon juice
Provides the sharp, acidic flavour that defines the sauce.
Sugar
Sweetens the sauce and balances the lemon's acidity.

The step that matters

Adding the cornstarch mixture. Cornstarch must be mixed with cold water before it goes into the boiling liquid, otherwise it clumps. Stirring constantly while it cooks keeps the sauce smooth as the starch swells and thickens.

Swap the lemon
