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 terrapins
Boil the terrapins for three hours until soft.
Carefully open them and remove the sand bag, spongy part, and gall without breaking it.
Cut the remaining terrapin into small pieces and place in a stew pan.
Make the stew
Add butter, wine, salt, black pepper, red pepper, and mustard to the pan.
Mash the egg yolks with a little butter and mix into the stew.
Stir everything together and stew for fifteen minutes.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Terrapins
- Form the main body of the stew, providing the meat that gives it its substance.
- Butter
- Adds richness and fat, giving the stew a smooth, rounded mouthfeel.
- Sherry or madeira wine
- Adds acidity and aromatic depth that brightens the rich meat and butter.
- Hard boiled egg yolks
- Mashed into the stew to thicken it and add a creamy, rich texture.
The step that matters
Removing the sand bag, spongy part, and gall. The gall is bitter and can taint the whole stew if it bursts, so it must be removed intact without breaking it.
