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.
