Why it works: Pepper and parsley 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 ↓
Scalloped Oyster
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Drain the oysters and reserve the liquid.
Make the sauce
In a saucepan, melt the butter and stir in the flour, salt, and pepper.
Gradually add the milk and reserved oyster liquid, stirring until thickened.
Assemble and bake
Layer the oysters in a baking dish, pour the sauce over them, and top with breadcrumbs and parsley.
Bake for 25-30 minutes until golden 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 flavor and the tender seafood base of the dish.
- Milk
- Forms the liquid base of the sauce, which thickens into a creamy binder.
- Butter
- Adds richness and fat, and carries the flour to form the roux.
- Flour
- Thickens the butter and milk into a smooth sauce that holds the oysters together.
- Breadcrumbs
- Form a crisp, golden topping that browns in the oven.
The step that matters
Thicken the sauce fully before layering. Flour thickens only when the roux and liquid are stirred and heated enough to gelatinize its starch. If the sauce is left thin, it will not coat the oysters or hold together in the dish.
Swap the parsley
How well each one fits the dish's main ingredients (oyster, milk, butter, flour, pepper):
- Nutmegfits about as well
- Parsleythe original
- Cinnamonfits about as well
- Thymefits less well
Fit is the average pairing score against oyster, milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
