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

What each ingredient does

Stock
Forms the liquid base and carries the soup's savory flavor.
Potatoes
Their released starch helps thicken the stock and adds body.
Milk
Adds creaminess and richness, and can thicken the soup when mixed with flour.
Flour
Its starch swells when heated in liquid, thickening the soup.

The step that matters

Thickening the stock. Flour added to hot liquid can clump. Mixing it smoothly with milk first and then stirring it in lets the starch disperse evenly. As the soup simmers, the starch swells and thickens it.

Swap the onion

How well each one fits the dish's main ingredients (potato, flour, pepper):

  1. Chivefits better
  2. Spinachfits better
  3. Okrafits better
  4. Onionthe original
