Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Potatoes
Break down into the body and thickness of the soup as they cook and are pressed.
Milk or cream
Adds richness and a smooth, creamy texture to the soup.
Butter
Adds fat for a richer, silkier mouthfeel in the finished soup.
Dry bread
Fried in lard, it becomes crisp and browned, contrasting with the smooth soup.
Lard
Conducts heat to brown the bread dice and adds savory fat.
Onions
Contribute aroma and mild sweetness when cooked in the soup.

The step that matters

Frying the bread dice until brown. The bread must fry in hot lard long enough to brown and crisp, since the Maillard reaction creates flavor and texture. Too little heat leaves it soggy, and too long burns it bitter.

Swap the celery

How well each one fits the dish's main ingredients (potato, pork, milk, butter, parsley, bread, onion):

  1. Thymefits better
  2. Garlicfits better
  3. Marjoramfits about as well
  4. Celerythe original

Fit is the average pairing score against potato, pork, milk, butter, parsley, bread, onion. Candidates are from the same food group and used in at least 100 recipes.
