The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Tomatoes
Provide the main body and tangy flavour of the soup.
Sugar
Balances the sharp acidity of the tomatoes with sweetness.
Soda
Neutralises some tomato acidity, mellowing the flavour.
Butter
Adds fat for richness and a smoother mouthfeel.
Flour
Thickens the soup as it is bound with the butter and liquid.

The step that matters

Bind. Flour must be mixed smoothly with the butter and hot liquid, or it forms lumps. Cooking it through removes raw flour taste and lets the starch swell to thicken the soup properly.

Swap the tomato

How well each one fits the dish's main ingredients (clove, sugar, butter, flour, onion):

  1. Leekfits better
  2. Shallotfits better
  3. Chivefits better
  4. Tomatothe original

Fit is the average pairing score against clove, sugar, butter, flour, onion. Candidates are from the same food group and used in at least 100 recipes.

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
