Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that the custard thickens and sets within.
- Corn starch
- Thickens the milk as it heats, giving the custard its body.
- Sugar
- Sweetens the custard and helps keep it smooth and glossy.
- Egg yolks
- Thicken the custard as they heat and add richness and a silky texture.
The step that matters
Cook over low heat, stirring constantly until thickened. Egg yolks can curdle or scramble if the custard overheats, while the starch needs enough heat to thicken. Gentle, constant stirring spreads heat evenly and keeps the custard smooth.
