Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Catfish
- Forms the main body of the soup, becoming flaky as it cooks.
- Salt pork
- Adds fat and savory flavor to the broth as it renders.
- Eggs
- Thicken the soup slightly when gently heated with the milk.
- Milk
- Adds richness and body, softening the broth's flavor.
- Celery
- Contributes aromatic flavor to the broth.
The step that matters
Adding the milk and eggs. Eggs thicken when heated, but if the liquid boils after they go in, they can curdle and turn grainy. Stir well and only heat through, as the record directs.
Swap the celery
How well each one fits the dish's main ingredients (catfish, pork, milk, egg):
- Garlicfits better
