Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Salmon Soup
Ingredients
Directions
Make the stock
In a stew-pan, combine the fowl, ham, anchovies, and salmon with butter over medium heat.
Stew for 30 minutes without browning.
Add 3 quarts of water and skim the surface.
Incorporate celery, onions, parsley, cloves, allspice, and white pepper.
Boil for 1.5 hours and strain through a fine sieve.
Make the soup
In a separate pan, melt butter and mix with flour until light brown.
Add the strained stock and stir until boiling, skimming off any butter.
Stir in pounded salmon mixed with cream and optional lobster spawn.
Add small pieces of boiled salmon just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Browned with butter to form a roux that thickens the soup.
- Butter
- Adds richness and carries flavour, and browns with the flour to form the roux.
- Cream
- Adds richness and smoothness to the pounded salmon enriching the soup.
- Salmon
- Gives the soup its main flavour, both as pounded fish and as boiled pieces.
- Fowl
- Provides a rich meaty base for the stock.
The step that matters
Browning the flour and butter. Cooking the flour in butter until light brown builds a roux that thickens the soup evenly. Stirring constantly prevents lumps and scorching, which would leave a bitter taste.
Swap the clove
