Why it works: Egg and oyster match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and 4,093 recipes mention both. Both carry 2-nonenal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: egg, wheat, fish, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Assemble
Layer the boiled cod sauce, hard-boiled eggs, and boiled cod in a deep pie dish.
Season the layers with pepper, coarse sea salt, and powdered mace.
Pour oyster sauce over the layered ingredients.
Cover with pie crust.
Bake and serve
Bake in a moderate oven at 350°F (175°C) for about 45 minutes.
Serve hot or cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Their proteins set when heated, giving the filling body and a firm, sliceable texture.
- Boiled cod
- Forms the main filling, supplying flaky, mild protein that softens into the layers.
- Oyster sauce
- Adds salty, savoury depth that seasons the layers as it spreads through the filling.
- Pie crust
- Encloses the filling and bakes to a golden, crisp top and edge.

- Nutmegbetter flavor fit
- Macethe original
Fit is the average pairing score against egg, pepper, oyster, sauce. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“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.
