Why it works: Parsley and pepper 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 ↓
Dressing Salt Fish
Ingredients
Directions
Prepare the fish
Soak the salt fish in cold water for 12 hours, or change the water for a shorter soak.
Place the fish in a skillet and cover with cold water. Boil for 15 minutes.
Change the water to fresh hot water and boil for another 15 minutes.
Make the dressing and serve
Serve the fish with drawn butter and garnish with parsley.
For a creamy dressing, boil 1 cup of cream, chopped parsley, butter, and pepper for 10 minutes.
If the cream is thin, add a beaten egg yolk and pour over the fish before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt fish
- Is the main protein, softened by soaking and boiling to remove excess salt.
- Cream
- Forms the richer dressing that coats the fish and adds smooth body.
- Egg yolk
- Thickens the cream dressing if it is too thin, adding body and richness.
The step that matters
Changing the water during cooking. Salt fish is very salty, so soaking and boiling in fresh water draw out salt. Skipping the water change or shortening the soak can leave the fish too salty.
Swap the parsley
How well each one fits the dish's main ingredients (fish, cream, butter, pepper, egg):
- Nutmegfits about as well
- Parsleythe original
- Tarragonfits about as well
- Capersfits less well
Fit is the average pairing score against fish, cream, butter, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
