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
Prepare the fish
Soak the salt codfish overnight in cold water, skin side up.
The next morning, wash the fish and place it in a large kettle with fresh cold water.
Cook and serve
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.
Boil the fish gently for five minutes, then drain and serve with melted butter or pork scraps.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt codfish
- Main protein; soaking draws out salt so the fish becomes mild and tender.
The step that matters
Keeping the water hot without boiling. Holding the water just below a boil lets the fish scald gently and stay tender and flaky. A hard boil toughens the proteins and breaks the fish apart.
Swap the potato
The recipe marks potato as optional. How well each one fits the dish's main ingredients (butter, parsnip):
- Leekfits better
- Beetrootfits better
- Turnipfits better
- Potatothe original
Fit is the average pairing score against butter, parsnip. Candidates are from the same food group and used in at least 100 recipes.
