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 ↓
Boiled Fish
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Wash the fish quickly in cold water and wipe dry.
Dredge lightly with flour and pepper.
Roll the fish in a napkin.
Cook and serve
Place the fish in a quart of boiling water with salt and vinegar.
Cook for about 10 minutes per pound for fresh fish.
Serve on a platter garnished with parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Main protein; boiling gently sets the flesh so it turns firm and flakes.
- Vinegar
- Adds a mild acidity that brightens the flavor of the fish.
- Flour
- Light coating that helps the pepper and seasoning cling to the surface.
The step that matters
Cook for about 10 minutes per pound. Fish proteins tighten as they cook, so overcooking squeezes out moisture and makes the flesh dry and tough. Timing by weight helps stop it just as it turns opaque and flakes.
Swap the parsley
How well each one fits the dish's main ingredients (fish, flour, pepper, vinegar):
- Tarragonfits better
- Turmericfits about as well
- Parsleythe original
- Capersfits about as well
Fit is the average pairing score against fish, flour, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
