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 ↓
Maryland Terrapins
Ingredients
Directions
Prepare the terrapins
Wash the terrapins in warm water.
Boil the terrapins in a pot of water until the shells crack.
Remove the bottom shell and cut each quarter separately.
Take out the gall from the liver and remove the eggs.
Stew and serve
Place the pieces in a saucepan, add the liquor, and cover with water.
Season with salt, cayenne, black pepper, and a little mace.
Add a little butter.
Let them stew for 30 minutes.
Just before serving, stir in a little flour to thicken.
Drop the eggs in just as you serve it.

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 of the stew, which becomes tender through long simmering.
- Butter
- Adds richness and a silky mouthfeel to the stew's broth.
- Flour
- Thickens the stew's liquid into a smooth, lightly body-filled sauce.
- Eggs
- Add richness and a soft, set texture when dropped into the hot stew.
The step that matters
Stirring in the flour just before serving. Flour thickens by swelling in hot liquid, so adding it at the end and stirring well prevents lumps and a pasty or raw-tasting sauce.
Swap the mace
How well each one fits the dish's main ingredients (pepper, butter, flour, egg):
- Parsleyfits better
- Nutmegfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against pepper, butter, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
