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

What each ingredient does

Butter
Carries the spiced aromatics and adds richness to the soup.
Onion
Browns to add sweetness and savoury depth to the base.
Tomatoes
Form the main body and acidic tomato flavour of the soup.
Flour
Thickens the strained soup so it becomes smooth and body-rich.

The step that matters

Browning the onion. Onion that is well browned develops sweet, deep flavours through the Maillard reaction. Pale onion leaves the soup tasting flat and raw, so it needs patient cooking over moderate heat.

Swap the mace

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

  1. Thymefits better
  2. Marjoramfits better
  3. Cinnamonfits better
  4. Macethe original
