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 ↓
Recipe for Terrapin
Ingredients
Directions
Prepare the terrapins
Place the terrapins in a tub of cold water and let them wash themselves.
Drain the water, add more water, and let them wash again.
Drop them into boiling water and cook until their feet are easy to remove, turning them occasionally.
Remove them from the shell and place them on a dish.
Save a little of the boiling water and strain it.
When the terrapins cool, pick the meat carefully, avoiding breaking the gall.
Split the entrails and cut them into pieces about an inch long.
Make the stew
In a stewpan, combine the meat with red pepper, black pepper, salt, and mace.
Add enough of the reserved boiling water to cover the meat and stew slowly for about 15 minutes.
Brown the flour with butter, then add the browned flour and butter to the stew.
Add the wine just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Terrapins
- Provide the meat that forms the body of the stew.
- Butter
- Adds richness and fat, and with browned flour gives the stew body and flavour.
- Flour
- Browned with butter, it thickens the stew and adds a toasted, nutty flavour.
- Wine
- Adds acidity and aroma to balance the rich, savoury stew.
The step that matters
Brown the flour with butter. Flour cooked in fat must brown evenly without burning. Properly browned roux gives colour and nutty flavour, while scorched flour tastes bitter and can spoil the whole stew.
Swap the mace
How well each one fits the dish's main ingredients (pepper, butter, flour, wine):
- Thymefits better
- Parsleyfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against pepper, butter, flour, wine. Candidates are from the same food group and used in at least 100 recipes.
