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 ↓
Fish Soup
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
Place the leftover fish in a pot.
Add enough water to cover the fish.
Season with salt and pepper.
Simmer and serve
Bring to a boil, then reduce heat and simmer for 20 minutes.
If desired, add herbs for extra flavor.
Strain the soup and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leftover fish
- Gives the soup its main flavor as it cooks and releases its taste into the water.
- Water
- Forms the broth and carries flavor from the fish throughout the soup.
The step that matters
Reduce to a gentle simmer after boiling. A hard, rolling boil breaks up the fish and clouds the broth, while a gentle simmer keeps the soup clearer and the fish tender.
