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 as flesh that becomes tender when simmered.
Salt pork
Adds fat and savoury flavour that enriches the broth as it cooks.
Eggs
Beaten and blended into the hot milk, they thicken and give the soup a richer body.
Milk
Adds creaminess and softness to the broth, mellowing its flavour.

The step that matters

Adding the egg and milk mixture. Eggs thicken when heated but can curdle or scramble if added to boiling liquid too quickly. Mixing them with warm milk first and adding gradually helps them blend smoothly into the soup.

Swap the celery

How well each one fits the dish's main ingredients (catfish, pork, milk, egg):
