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

  1. Skim the stock carefully.

  2. Heat the stock to boiling.

Make the soup

  1. Add the minced fish, pepper, and salt, and let simmer.

  2. Heat the milk in a double boiler.

  3. When hot, pour the milk over the beaten egg, mix well, and add with the crumbs to the hot stock.

  4. Serve.

Variations

  1. If no stock is available, use one cup hot water and two cups milk instead.

  2. If eggs are scarce, omit the egg and substitute a tablespoon of flour rolled in one tablespoon of butter.

  3. Optionally, add a cupful of diced potatoes and a tablespoon of minced parsley, onion, bay leaf, or sweet herbs.

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):

  1. Nutmegfits about as well
  2. Parsleythe original
  3. Cinnamonfits about as well
  4. 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.
