Why it works: Parsley and capers match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,550 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

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.
Prepare
Preheat the oven to 350°F (175°C).
Butter a pudding dish and cover the bottom with oysters.
Assemble
Sprinkle oysters with cracker crumbs, bits of butter, parsley, celery salt, capers, and paprika.
Moisten with heated cream or milk thickened with white roux and allowed to cool.
Add another layer of oysters, more seasoned crumbs, and cream until the dish is full.
Top with crumbs thickly dotted with butter.
Bake
Bake covered until it bubbles, then uncover and brown lightly for about 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Form the main body of the dish and release their briny flavor as they cook.
- Butter
- Adds richness and helps the crumb topping brown.
- Cracker crumbs
- Absorb liquid and give the layers body, with a crisp top when browned.
- Cream or milk
- Provides moisture and, with the roux, forms a smooth sauce around the oysters.
- White roux
- Thickens the cream so it coats the oysters rather than running off.
The step that matters
Thickening the cream with roux. The roux must be fully cooked and the cream heated before it goes in, then allowed to cool slightly. Lumps or a thin sauce can result if it is added too hot or too cold, and the sauce sets the texture of the whole dish.
Swap the celery
How well each one fits the dish's main ingredients (oyster, butter, parsley, capers, cream):
- Tarragonfits better
- Nutmegfits about as well
- Thymefits about as well
- Celerythe original
Fit is the average pairing score against oyster, butter, parsley, capers, cream. Candidates are from the same food group and used in at least 100 recipes.
