Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they set with heat, giving it body.
- Corn starch
- Thickens the liquid when heated, giving the custard a smooth, set texture.
- Sugar
- Adds sweetness and balances the bitterness of the coffee.
- Milk
- Forms the creamy liquid base that the eggs and starch thicken.
The step that matters
Stir the custard until smooth. Eggs can curdle and starch can clump if the mixture is not stirred while it thickens. Constant stirring keeps the custard smooth and evenly thickened.
