Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Form the main body of the soup and give it its sweet, earthy flavour.
- Onions
- Add savoury depth and aroma as they soften during the long simmer.
- Celery
- Adds a fresh, aromatic background note to the vegetable base.
- Butter
- Adds fat for a richer flavour and a smoother, rounder mouthfeel.
- Stock
- Supplies the main liquid and savoury flavour to thin and season the pulp.
The step that matters
Rub the mixture through a fine sieve. Pressing the cooked vegetables through a fine sieve breaks down fibres and removes skins and stringy bits, which gives the soup a smooth, even texture. Skipping or rushing this step leaves the soup grainy.
Swap the onion
How well each one fits the dish's main ingredients (carrot, celery, vinegar, sugar, butter):
- Mustardfits better
- Capsicumfits better
- Parsnipfits better
- Onionthe original
Fit is the average pairing score against carrot, celery, vinegar, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
