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

What each ingredient does

Pearl sago (in the method)
Swells when cooked until clear, giving the soup a thickened, slightly gelatinous body.
Tomatoes (in the method)
Provide the main body, colour and acidic tomato flavour of the soup.
Butter
Adds richness and a smooth, rounded mouthfeel to the finished soup.

The step that matters

Cooking the sago until clear. Sago must be cooked slowly and fully, because its starch only becomes clear and tender once the granules have gelatinized; undercooked sago stays opaque and chewy.

Swap the onion

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

  1. Carrotfits better
  2. Shallotfits better
  3. Potatofits better
  4. Onionthe original

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