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

What each ingredient does

Onion
Softened in butter to build a sweet, mild base for the sauce.
Butter
Carries the onion and adds rich flavour and fat to the sauce.
Flour
Thickens the cream into a smooth, cohesive sauce.
Cream
Forms the body of the sauce and adds richness and moisture.
Hard-boiled eggs
Provide the main protein and soft, tender texture in the dish.

The step that matters

Heating the eggs without boiling. Once the sauce is thickened, boiling can cause the cream to separate and the egg whites to toughen and turn rubbery. A gentle toss for a short time warms the eggs while keeping the sauce smooth.

Swap the onion

How well each one fits the dish's main ingredients (butter, flour, cream, pepper, nutmeg, egg):
