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 of the soup, becoming tender and flavourful as it simmers.
- Salt pork
- Adds savoury, fatty richness to the broth as it cooks down.
- Sweet milk
- Makes the soup creamy and mellows its flavour when added hot.
- Eggs
- Thicken the hot soup slightly and add richness and body when beaten in.
- Butter
- Adds fat and a smooth, rounded finish to the broth.
The step that matters
Adding the eggs and milk. Eggs can curdle or scramble if the soup is boiling hard when they go in. Adding the hot milk and beaten eggs to the pot gently, and keeping the heat controlled, helps the soup stay smooth and thickened.
