Why it works: Anchovy and sauce are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 2,057 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Cat-fish Soup
Ingredients
Directions
Make the broth
Skin the catfish, remove the heads, and cut them into pieces.
In a pot, combine the fish, onion, and cold water. Boil until the fish falls apart.
Strain the mixture and return the liquid to the pot.
Add the corn starch mixture and stir until thickened.
Add the butter gradually, one teaspoon at a time, stirring well.
Season with salt, pepper, celery, and anchovy sauce.
Finish and serve
In a separate pot, heat the milk with the beaten eggs and parsley for one minute.
Add the milk mixture to the hot soup, stir well, and serve.
Garnish with sliced lemon and serve with oyster crackers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Catfish
- Provides the main body and flavor of the soup as it breaks down in the broth.
- Corn starch
- Thickens the broth into a smooth, lightly body-filled soup when heated.
- Milk
- Adds creaminess and softens the flavor of the broth.
- Eggs
- Enrich the soup and add body as they gently set in the hot milk mixture.
- Butter
- Adds richness and a silky mouthfeel to the finished broth.
The step that matters
Adding the milk and egg mixture to the soup. Eggs set when they get too hot and can curdle or turn grainy. Stirring the milk-egg mixture well and adding it to hot soup gradually keeps the eggs smooth and evenly blended.
Swap the celery
How well each one fits the dish's main ingredients (catfish, onion, milk, butter, corn, anchovy, sauce):
- Garlicfits better
- Capersfits better
- Parsleyfits about as well
- Celerythe original
Fit is the average pairing score against catfish, onion, milk, butter, corn, anchovy, sauce. Candidates are from the same food group and used in at least 100 recipes.
