Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Oysters Au Gratin
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the oysters
Boil the oysters in their liquor until the edges curl, then set aside.
Make the filling
In a bowl, mix the toasted bread crumbs, chopped celery, parsley, melted butter, mushrooms, Lea & Perrin's sauce, catsup, cayenne pepper, and salt.
Add a spoonful or two of the oysters' liquor to the mixture.
Bake and serve
Grease deep oyster shells and fill them with the mixture, topping with butter and bread crumbs.
Bake in a hot oven at 400°F (200°C) until brown, then serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Cooked briefly in their liquor until the edges curl, giving tender, briny meat that holds its shape when baked.
- Toasted bread crumbs
- Absorb the butter and liquor to form a moist, binding filling and a crisp, browned topping.
- Melted butter
- Adds richness and moisture to the filling and helps the topping brown.
- Mushrooms
- Add earthy flavour and moisture to the filling.
- Celery
- Adds a crisp, fresh, slightly vegetal note that balances the rich butter.
The step that matters
Bake until brown, then serve immediately. Oysters overcook quickly in a hot oven and turn rubbery. Baking only until the topping browns keeps the oysters tender and the filling moist, and serving right away preserves that texture.

Fit is the average pairing score against oyster, bread, parsley, butter, mushroom, sauce, pepper. Candidates are from the same food group and used in at least 100 recipes.
