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
Soak the salt fish in cold water overnight.
Expose the fish to air for some time, then soak it again until softened.
Brush the fish clean and wash it thoroughly.
Place the fish in a fish kettle with plenty of cold water.
Heat the fish slowly, keeping it just below simmering for 45 minutes to 1 hour, depending on its weight.
Skim off any scum that forms during cooking.
Serve the fish on a hot napkin, optionally garnished with chopped eggs.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
Swap the parsley
How well each one fits the dish's main ingredients (fish, butter, flour, pepper):
- Parsleythe original
- Capersfits about as well
- Turmericfits less well
- Tarragonfits less well
Fit is the average pairing score against fish, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
