Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Mackerel Pie
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 the fish
Clean the mackerel, remove the heads and tails, and cut each fish into four pieces.
Rub the pieces with chopped fennel, pepper, and salt.
Toss the mackerel in butter and let it cool.
Sprinkle the cooled fish with pounded sugar.
Assemble and bake
Lay the fish in a dish on slices of fresh butter.
Add forcemeat balls made with chopped oysters, bread-crumbs, spices, and eggs.
Cover with a top crust.
Bake gently at 350°F (175°C) for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Forms the main filling and becomes tender and flaky as it bakes gently.
- Eggs
- Bind the forcemeat balls so they hold their shape in the pie.
- Butter
- Adds richness and moisture to the fish and the dish.
- Pounded loaf sugar
- Adds a touch of sweetness that balances the salt and rich fish.
The step that matters
Let the mackerel cool before layering. Adding sugar and layering while the fish is still hot can cause the butter to melt out and make the filling greasy and loose. Cooling keeps the fat in place during baking.
Swap the fennel
How well each one fits the dish's main ingredients (pepper, butter, sugar, oyster, bread, egg):
- Nutmegfits better
- Parsleyfits better
- Cinnamonfits better
- Fennelthe original
Fit is the average pairing score against pepper, butter, sugar, oyster, bread, egg. Candidates are from the same food group and used in at least 100 recipes.
