Why it works: Fish and cocoa work together. They rank in the top 19% of all ingredient pairs, and cooks put them together in 25 recipes. Both carry 2-undecenal, which smells sweet. The science ↓
Boiled Rockfish
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.
Place the cleaned rockfish in a pot and cover with water.
Add ½ teaspoon of coarse sea salt for every pound of fish.
Boil slowly until the meat is tender and separates easily from the bones, about 1 hour for a large fish.
Serve on a hot dish, garnished with sliced hard-boiled eggs around and over the fish.
Serve cocoa sauce on the side.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rockfish
- Forms the main body of the dish; slow boiling turns its flesh tender and flaky.
- Coarse sea salt
- Seasons the fish and water, flavouring the mild flesh as it cooks.
The step that matters
Boil slowly until the meat is tender. Boiling too hard can toughen and break up the delicate fish flesh. A gentle simmer cooks it evenly so it becomes tender and separates cleanly from the bones.
Swap the cocoa
How well each one fits the dish's main ingredients (fish, egg, sauce):
- Peasfits better
- Walnutfits better
- Beansfits better
- Cocoathe original
Fit is the average pairing score against fish, egg, sauce. Candidates are from the same food group and used in at least 100 recipes.
