Why it works: Butter and milk 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 ↓
New England Codfish Balls
Ingredients
Directions
Prepare the mixture
Place the potatoes in a saucepan and add the washed and finely picked codfish on top.
Cover with boiling water and cook until the potatoes are tender, about 20 minutes.
Drain the water and let the saucepan sit on the back of the stove to dry out.
Beat the mixture with a fork or whisk until light.
Add the butter and well-beaten egg, and mix again.
If the mixture is too stiff, add a teaspoon of hot milk.
Fry and serve
Drop by teaspoonfuls into boiling hot fat, using a frying basket.
Fry no more than four balls at a time.
Reheat the fat between each batch.
Drain the balls on soft paper and serve hot.
For lunch, serve with tartar sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the balls and give them a soft, tender body.
- Salt codfish
- Supplies the savoury, salty flavour that defines the dish.
- Egg
- Binds the mixture so the balls hold their shape while frying.
- Baking powder
- Lightens the mixture so the balls puff and stay tender when fried.
- Butter
- Adds richness and moisture to the mixture.
The step that matters
Drying the mixture on the stove. Letting the drained potato and cod sit over residual heat evaporates surface water. Wet mixture makes the balls soggy and prone to breaking apart in hot fat.
Swap the white pepper
How well each one fits the dish's main ingredients (potato, butter, egg, milk):
- Nutmegfits better
- Cinnamonfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against potato, butter, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
