Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down during boiling and pressing to give the soup body and a thick, smooth texture.
- Milk
- Adds creaminess and mild sweetness, rounding out the broth.
- Cornstarch
- Thickens the liquid when boiled, giving the soup a fuller body.
- Salt pork
- Renders fat and savory flavor into the broth as the vegetables cook.
- Onions
- Build a sweet, savory base of flavor as they soften in the liquid.
The step that matters
Boil after adding the cornstarch and milk. Cornstarch only thickens fully when it reaches a boil, so the soup must be brought back to a boil and kept there for the full 3 minutes. Boiling milk too hard can scorch it on the pot bottom, so stir often.
Swap the turnip
How well each one fits the dish's main ingredients (pork, onion, potato, celery, milk, butter, pepper):
- Carrotfits better
- Capsicumfits better

- Turnipthe original
Fit is the average pairing score against pork, onion, potato, celery, milk, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
