Why it works: Biscuit and onion work together. They rank in the top 8% of all ingredient pairs, and cooks put them together in 428 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
And Haddocks
Ingredients
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.
Prepare the stuffing
Scale and clean the haddock, leaving the breast largely intact.
In a bowl, combine egg yolks, chopped oysters, anchovies, biscuit or bread, parsley, onion, mace, black pepper, allspice, and salt.
Melt butter in a pan and stir the mixture over heat until thick, adding more biscuit or flour if needed.
Stuff and bake
Stuff the haddock with the mixture and sew up the slit.
Bake in a 350°F (175°C) oven, basting with butter and adding more butter on top.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Bind the stuffing and set it firm when heated, giving a thick texture.
- Biscuit or grated bread
- Absorbs moisture and gives the stuffing body so it holds together.
- Oysters
- Add a briny, savory flavor that seasons the stuffing from within.
- Anchovies
- Contribute salty, savory depth that enhances the fish flavor.
- Butter
- Adds richness and helps the fish brown and stay moist while baking.
The step that matters
Stirring the stuffing until thick. Egg yolks set when heated, so stirring over heat until thick gives a stable stuffing. Heating too hard or too long can scramble the yolks and make the mixture grainy.
Swap the mace
How well each one fits the dish's main ingredients (fish, haddock, egg, oyster, biscuit, parsley, onion):
- Capersfits better
- Thymefits better
- Nutmegfits better
- Macethe original
Fit is the average pairing score against fish, haddock, egg, oyster, biscuit, parsley, onion. Candidates are from the same food group and used in at least 100 recipes.
