Why it works: Potato and butter are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Breakfast Dish
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Boil the potatoes for 20 minutes.
Drain the water and mash the potatoes with the codfish.
Add the butter and the egg, mixing well.
Bake and serve
Transfer the mixture to a pudding dish.
Bake in a 400°F (200°C) oven until lightly browned.
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
- Codfish
- Provides the main savoury flavour and body of the pudding.
- Potatoes
- Mashed, they give the pudding its soft, bulky body.
- Egg
- Binds the mashed mixture so it holds together when baked.
- Butter
- Adds richness and moisture, and helps the top brown.
The step that matters
Mashing the potatoes with the codfish. Potatoes must be drained well and mashed smooth before the egg and butter go in. Excess water makes the mixture loose and wet, so it may not set firmly or brown evenly in the oven.

Fit is the average pairing score against egg, butter. Candidates are from the same food group and used in at least 100 recipes.
