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

What each ingredient does

Eggs
Proteins set with heat to give the custard its firm, sliceable structure.
Sugar
Adds sweetness and balances the savoury, eggy flavour of the custard.
Milk
Forms the liquid base that gives the custard its smooth, creamy moisture.
Vanilla
Adds aroma and a rounded flavour to the sweet custard.

The step that matters

Remove the cups when the custard is set. Egg proteins coagulate with gentle heat, but overcooking tightens them further, squeezing out liquid and making the custard grainy, watery or curdled. Check early and take the cups out as soon as they are set.
