Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Binds the butter and flour and thickens the sauce as it heats.
- Butter
- Adds richness and a smooth, silky mouthfeel to the sauce.
- Flour
- Thickens the sauce so it clings to the chicken.
- Madeira wine
- Adds sweetness and a deep, fortified wine aroma at the end.
The step that matters
Adding the butter mixture in two parts. Adding the butter, flour and yolk mixture all at once can cause it to clump or curdle in hot liquid. Stirring well after each addition helps it blend evenly and thicken smoothly.
