Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Provides the main protein and the soft, runny yolk that enriches the dish.
- Cream or milk
- Forms the base of the sauce, adding richness and a smooth, creamy body.
- Corn starch
- Thickens the hot cream or milk into a smooth sauce as its starch gelatinizes.
- Butter
- Adds fat for richness and a silky mouthfeel to the sauce.
The step that matters
Thicken the sauce with corn starch. Corn starch must be fully mixed in and brought to a boil to gelatinize and thicken. Lumps form if it is added to cold liquid without stirring, and the sauce stays thin if it is not boiled.
