Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Chicken Terrapin
Ingredients
Directions
Prepare the chicken
Boil the chicken until perfectly tender, then pick it into small pieces.
In a porcelain stew-pan, combine the chicken with boiling water.
Make the sauce
Cream together the butter and flour until smooth, then beat in the egg yolks.
Add the butter mixture to the hot chicken gradually to prevent lumps.
Boil for 1-2 minutes, stirring constantly.
Season with salt and pepper to taste.
Finish
Remove from heat and stir in the Madeira or Sherry wine.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce with fat, giving it a smooth, rich mouthfeel.
- Egg yolks
- Thicken the sauce as they heat, giving it a creamy body.
- Flour
- Thickens the butter mixture so it blends smoothly into the hot chicken.
- Madeira or sherry wine
- Adds acidity and aromatic depth to the finished sauce.
The step that matters
Add the butter mixture to the hot chicken gradually. Adding the butter and flour mixture slowly while stirring lets it disperse evenly. Adding it all at once can cause lumps, and egg yolks can curdle if the mixture overheats, so keep the heat moderate and stir constantly.
