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 ↓
Terrapins
Ingredients
Directions
Prepare the terrapins
Boil the terrapins in water for 10 minutes.
Remove them and rub off the skin from the head, neck, and claws with a coarse cloth.
Boil the cleaned terrapins in fresh water with a little salt until the claws are soft, which may take up to 3 hours.
Carefully open the terrapins and remove the sand-bag, spongy part, and gall without breaking them.
Cut the remaining meat into small pieces and place in a stew pan.
Make the stew
Add ½ cup of butter, ⅓ cup of Sherry or Madeira wine, salt, black pepper, red pepper, and mustard to taste.
Mash the yolks of 2 hard boiled eggs with a little butter and mix into the stew.
Cook the mixture for 15 minutes and serve hot.

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, which is cooked until the claws are tender.
- Butter
- Adds richness and fat, giving the stew a smooth, rounded mouthfeel.
- Sherry or madeira wine
- Adds acidity and aromatic depth to the stew's flavour.
- Hard boiled egg yolks
- Mashed into the stew to thicken it and add richness.
The step that matters
Boil the terrapins until the claws are soft. Terrapin meat and connective tissue toughen if undercooked, and the claws only become tender after long, gentle simmering. Judge doneness by tenderness, not by the clock, since the record notes it may take up to 3 hours.
