Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
To Boil Salt Fish
Ingredients
Directions
Prepare the fish
Soak the very salt, dry fish for a night in a large quantity of cold water.
Let the fish lie exposed to the air for some time.
Put it back into water and repeat soaking and airing until it is well softened.
Brush the fish very clean.
Wash the fish thoroughly.
Cook the fish
Put the fish with abundance of cold water into the fish kettle.
Place the kettle near the fire and heat very slowly.
Keep it just on the point of simmering, never allowing it to boil.
Clear off the scum with great care from the beginning.
Cook from three quarters of an hour to a full hour, according to its weight; use less time if it is small and thin.
Serve
Dish the fish upon a hot napkin.
Serve with egg sauce and boiled parsneps.
Sometimes strew the fish thickly with chopped eggs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt cod
- Salt curing is what the soaking and airing gradually undo to soften the fish.
- Butter
- Adds richness and fat to the sauce served with the fish.
- Vinegar
- Adds sharpness that balances the richness of the fish and sauce.
The step that matters
Keep the water just below a simmer. Boiling agitates and breaks up the delicate flakes of fish and drives the scum into the liquid, so gentle heat keeps the fish moist and intact.
Swap the parsley
How well each one fits the dish's main ingredients (butter, pepper, vinegar):
- Tarragonfits about as well
- Parsleythe original
- Thymefits less well
- Dillfits less well
Fit is the average pairing score against butter, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
