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 corn starch thickens into a custard.
- Corn starch
- Thickens the hot milk as its starch granules swell and gel when heated.
- Sugar
- Adds sweetness and balances the flavour of the milk.
- Melted butter
- Adds fat for richness and a smoother, silkier mouthfeel.
- Vanilla extract
- Adds aroma that rounds out the custard's flavour.
The step that matters
Cooking the thickened milk with constant stirring. Corn starch only thickens fully when the mixture is hot and stirred, because the granules must swell evenly. Stopping to stir or letting it sit can cause lumps or scorching on the base of the pan.
