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 ↓
Oyster Loaf
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the oysters
Drain the oysters and bring them to a boil in a pot.
Drain again and add enough milk to the oyster liquor to make 1 pint.
Make the sauce
In a separate bowl, rub together the butter and flour.
Add the milk and oyster liquor mixture to the butter and flour, stirring until boiling.
Add the oysters, beaten egg, parsley, salt, and pepper, and mix well.
Prepare the bread
Create a boat from stale bread by removing the center, brushing with melted butter, and baking in a 400°F (200°C) oven until light brown.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main filling and flavour of the dish.
- Butter
- Adds richness and flavour, and helps coat the bread so it browns.
- Flour
- Rubbed with butter and thickens the milk mixture into a sauce.
- Milk
- Forms the liquid base of the sauce with the oyster liquor.
- Beaten egg
- Helps bind and thicken the filling as it is mixed in.
The step that matters
Stirring the milk mixture until boiling. Flour thickens liquid only when it is heated, and stirring prevents lumps from forming as the starch hydrates. Stop stirring too early and the sauce may stay thin and grainy.
Swap the parsley
How well each one fits the dish's main ingredients (oyster, milk, butter, flour, egg, pepper, bread):
- Nutmegfits about as well
- Parsleythe original
- Cinnamonfits about as well
- Capersfits about as well
Fit is the average pairing score against oyster, milk, butter, flour, egg, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
