Why it works: Potato and parsnip work together. They rank in the top 6% of all ingredient pairs, and cooks put them together in 353 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Salt-fish Dinner
Ingredients
Directions
Soak and scald
Soak the salt codfish overnight in cold water with the skin side up.
The next morning, wash the fish and place it in a large kettle with plenty of fresh cold water.
Set the kettle on the back of the stove to keep the water hot without boiling.
Let the fish scald until just before dinner time.
Cook and serve
Boil the fish gently for five minutes, then drain it.
Serve with melted butter or pork scraps, alongside boiled potatoes, beets, and parsnips.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt codfish
- Provides the main protein; soaking and gentle heat restore its moisture and tenderness.
- Potatoes
- Provide starchy bulk that soaks up the flavour of the butter and fish.
- Beets
- Add natural sweetness and earthy flavour that balances the salty fish.
The step that matters
Keep the water below a boil while the fish scalds. Salt cod turns tough and rubbery when it boils hard. Holding the water just below a simmer lets the fish soften gradually and stay moist and flaky.
Swap the parsnip
How well each one fits the dish's main ingredients (butter, potato):
- Chivefits better
- Onionfits better
- Asparagusfits better
- Parsnipthe original
Fit is the average pairing score against butter, potato. Candidates are from the same food group and used in at least 100 recipes.
