Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Oysters on Toast
Ingredients
Directions

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavour and bulk of the dish once cut and cooked in butter.
- Egg yolks
- Thicken the mixture as they cook, turning it into a creamy custard-like sauce.
- Cream
- Adds richness and moisture, and softens the set of the egg yolks.
- Butter
- Adds fat and richness, carrying flavour through the oysters.
The step that matters
Cook until the mixture thickens. Egg yolks set at a gentle heat. If the mixture gets too hot or cooks too long, the yolks can scramble and turn grainy instead of smooth and creamy.
Swap the mace
How well each one fits the dish's main ingredients (oyster, cream, egg, parsley, pepper, butter):
- Nutmegfits better
- Tarragonfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against oyster, cream, egg, parsley, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
