Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Terrapin, Family Style
Ingredients
Directions
Prepare the terrapin
Place the live terrapin in cold water for 1 hour to clean itself.
Plunge it into boiling water for 2 minutes to remove the outer skin.
Boil the cleaned terrapin in salted water for 30-40 minutes.
Remove the meat and entrails, discarding the gall.
Cut the meat and entrails into small pieces, keeping the liver and eggs separate.
Make the stew
Combine the meat, butter, lemon juice, lemon zest, salt, pepper, nutmeg, sherry, and brandy in a saucepan.
Cover and cook until the meat is tender.
Thicken and serve
Melt a small piece of butter in a saucepan. Add flour and cook until golden. Add some terrapin stock to the flour mixture and stir until smooth.
Pour the roux into the terrapin mixture.
Add the eggs and liver to the mixture. Cook for 5 more minutes.
Finish with a small piece of butter.
Serve very hot, removing the lemon zest first.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Terrapin
- Provides the main meat, which becomes tender through long simmering.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the finished stew.
- Flour
- Thickens the cooking liquid into a smooth sauce when cooked into a roux.
- Sherry
- Adds acidity and a nutty, aromatic depth to the stew.
- Brandy
- Adds warmth and aroma to the stew.
- Eggs
- Enrich the sauce and add body as they set with the heat.
The step that matters
Adding the roux to the terrapin mixture. Flour must cook until golden to lose its raw starch taste, and the roux should be stirred smooth before being poured in. Stirring keeps lumps from forming, so the sauce thickens evenly.
