Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Fish Pie
Ingredients
Directions
The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Boil the haddock until cooked, then remove all bones and skin.
Layer and bake
In a tin dish, layer the fish, followed by a few oysters and a sprinkle of crushed crackers.
Season with salt, pepper, and nutmeg if desired.
Repeat layering, adding crumbs of butter and pouring in the oyster liquor and milk.
Top with a final layer of crushed crackers sprinkled with butter.
Bake in a 400°F (200°C) oven for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Forms the flaky, substantial body of the pie.
- Oysters
- Adds a briny, savoury flavour that carries through the dish.
- Crackers
- Crushed crumbs soak up liquid and help bind the layers together.
- Milk
- Adds moisture and richness, keeping the layers from drying out in the oven.
- Butter
- Adds fat for richness and helps the top crumbs brown in the oven.
The step that matters
Layering and moisture. Pour the oyster liquor and milk evenly over the layers before baking. Crumbs and fish absorb liquid as they heat, so too little liquid leaves the pie dry, while the proteins in the fish set as it bakes.
Swap the nutmeg
The recipe marks nutmeg as optional. How well each one fits the dish's main ingredients (haddock, oyster, pepper, milk, butter):
- Parsleyfits about as well
- Nutmegthe original
- Thymefits about as well
- Capersfits about as well
Fit is the average pairing score against haddock, oyster, pepper, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
