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 ↓
Baked Halibut Steak
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
Preheat the oven to 350°F (175°C).
Butter a baking dish and place a layer of halibut steak in the bottom.
Sprinkle lightly with bread or cracker crumbs.
Make the custard
In a bowl, mix the beaten eggs, milk, salt, pepper, nutmeg, and sugar to create the custard mixture.
Layer and bake
Pour half of the custard mixture over the halibut.
Add another layer of halibut and sprinkle with more crumbs.
Pour the remaining custard mixture over the top.
As the custard thickens at the sides, loosen it with a spoon and pile it on top.
Repeat this process several times until browned.
Bake for 45 minutes or until the fish is cooked through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Halibut steak
- Forms the main body of the dish, cooking through into flaky layers in the custard.
- Eggs
- Set the custard, giving the layers a firm, sliceable structure as they bake.
- Milk
- Forms the liquid base of the custard, keeping the fish moist as it bakes.
- Butter
- Greases the dish and adds richness and browning to the surface.
- Bread or cracker crumbs
- Absorb custard between layers and help the top brown.
The step that matters
Layering and pile-up of the custard. Custard that is not loosened and piled over the top can thicken unevenly at the sides, leaving the surface pale and the fish underneath dry. Spooning it back over the top keeps the layers evenly moist and helps the surface brown.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, bread, egg, milk, pepper, sugar):
- Cinnamonfits about as well
- Nutmegthe original
- Parsleyfits less well
- Cardamomfits less well
Fit is the average pairing score against butter, bread, egg, milk, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
