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

What each ingredient does

Chicken
Provides the main protein, which becomes tender during the long gentle simmer.
Flour
Thickens the stock into a smooth sauce when cooked with the melted butter.
Butter
Adds richness and carries the flour to form the thickening base.
Sherry wine
Adds acidity and aromatic depth to the sauce.
Hard-boiled eggs
Add richness and a soft, creamy contrast as a topping.

The step that matters

Simmer for 1 hour. A gentle simmer keeps the sauce from scorching and lets the chicken become tender without toughening. Too hard a boil can make the sauce break and the meat dry and stringy.

Swap the lemon

How well each one fits the dish's main ingredients (butter, flour, chicken, pepper, sherry, wine, egg):
