Why it works: Pepper and mustard are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 15,430 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Terrapin Stew
Ingredients
Directions
Prepare the terrapin
Boil the terrapin for three hours until soft.
Carefully open the terrapin and remove the sandbag, spongy part, and gall without breaking them.
Cut the remaining terrapin into small pieces.
Make the stew
In a stew pan, combine the terrapin pieces, butter, wine, salt, black pepper, red pepper, mustard, and mashed egg yolks, then mix well and stew for 15 minutes.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Terrapin
- Forms the main body of the stew, providing the meat that becomes tender after long boiling.
- Butter
- Adds richness and moisture, rounding out the flavour of the stew.
- Sherry or madeira wine
- Adds acidity and aromatic depth to the stewing liquid.
- Hard boiled egg yolks
- Mashed into the stew, they thicken the liquid and add richness.
The step that matters
Opening the terrapin without breaking the gall. The gall is bitter and can spoil the flavour of the meat if it bursts, so it must be removed intact while the shell is opened.
