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 ↓
Fish Soup
Ingredients
Directions
Prepare the stock
Skim the stock carefully.
Heat the stock to boiling.
Make the soup
Add the minced fish, pepper, and salt, and let simmer.
Heat the milk in a double boiler.
When hot, pour the milk over the beaten egg, mix well, and add with the crumbs to the hot stock.
Serve.
Variations
If no stock is available, use one cup hot water and two cups milk instead.
If eggs are scarce, omit the egg and substitute a tablespoon of flour rolled in one tablespoon of butter.
Optionally, add a cupful of diced potatoes and a tablespoon of minced parsley, onion, bay leaf, or sweet herbs.
Nutrition, whole recipe (rough)
Counts 9 of 11 ingredients. The other 2 aren't in our nutrition table and add nothing above, so the real totals are higher.

Flour and butter 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
What each ingredient does
- Fish
- Provides the main body and flavour of the soup.
- Egg
- Binds the soup and gives it a slightly thickened, smooth texture.
- Fine crumbs
- Absorb liquid and help thicken the soup.
- Milk
- Adds richness and a mild, creamy body to the soup.
- Soup stock
- Forms the savoury liquid base that carries the other ingredients.
The step that matters
Adding the egg and milk mixture to the hot stock. Pouring the milk over the beaten egg tempers it, so the egg warms gently instead of scrambling. Adding it to hot stock while stirring keeps the egg smooth and evenly blended.
Swap the parsley
How well each one fits the dish's main ingredients (milk, flour, butter, fish, egg, pepper):
- Nutmegfits about as well
- Parsleythe original
- Cinnamonfits about as well
- Capersfits about as well
Fit is the average pairing score against milk, flour, butter, fish, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
