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 Codfish
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
Soak the codfish in cold water for several hours.
In a bowl, mix the mashed potatoes with the egg, milk, butter, salt, and pepper.
Transfer the mixture to a baking dish.
Top and bake
Cover the top with bread crumbs.
Moisten the bread crumbs with a little milk.
Bake in a 350°F (175°C) oven for 30 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Forms the bulk and soft, creamy body of the dish.
- Egg
- Binds the mixture and helps it set when baked.
- Milk
- Adds moisture and keeps the mixture soft while it bakes.
- Butter
- Adds fat for richness and a tender texture.
- Bread crumbs
- Form a crisp, golden topping as they brown in the oven.
The step that matters
Moisten the bread crumbs with a little milk. Dry crumbs can scorch or stay pale on the surface. A little milk helps them brown evenly and form a crisp, golden crust rather than drying out.
Swap the potato
How well each one fits the dish's main ingredients (egg, milk, butter, pepper, bread):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Tomatofits less well
Fit is the average pairing score against egg, milk, butter, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
