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

What each ingredient does

Flour
Thickens the butter and milk into a smooth white sauce.
Butter
Enriches the sauce and softens the onions, adding richness and flavour.
Milk
Forms the liquid base of the white sauce, which thickens as it heats.
Onions
Add sweetness and savoury depth as they soften in butter.
Hard-boiled eggs
Provide the main body and protein of the dish, set and firm when baked.
