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 ↓
Terrapin Salad
Ingredients
Directions
Prepare the terrapins
Boil the terrapins until the shells come off easily and the nails pull out.
Cut the terrapins into small pieces.
Carefully remove the sand-bag and gall.
Make the dressing
Remove the yolks from the hard-boiled eggs.
Rub the yolks into a powder with the butter until creamy and light.
Add the flour to the egg and butter mixture.
Combine and finish
Combine this mixture with the terrapin meat in a saucepan.
Season with cayenne pepper and salt.
Let it boil for one to two minutes.
Add wine.
Add mace if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Terrapins
- Provide the main meat, which becomes tender after boiling and cutting.
- Hard-boiled eggs
- Yolks are rubbed with butter to form a rich, creamy base for the salad.
- Sweet butter
- Adds fat and richness, carrying the yolks into a smooth, creamy texture.
- Flour
- Thickens the egg and butter mixture so it clings to the terrapin meat.
The step that matters
Rub the yolks into a powder with the butter until creamy and light. Yolks that stay lumpy won't blend smoothly into the butter, leaving a grainy dressing. Working them thoroughly lets the fat and yolk emulsify into a uniform, creamy base before the flour and meat are added.
Swap the mace
The recipe marks mace as optional. How well each one fits the dish's main ingredients (egg, butter, flour, pepper, wine):
- Parsleyfits better
- Tarragonfits better
- Nutmegfits better
- Macethe original
Fit is the average pairing score against egg, butter, flour, pepper, wine. Candidates are from the same food group and used in at least 100 recipes.
