Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Parsnips
- Provide the main body and sweet, earthy flavour of the soup.
- Onions
- Add savoury depth and aromatic sweetness as they soften in the stock.
- Celery
- Adds a fresh, herbal aroma that rounds out the vegetable flavour.
- Milk
- Adds richness and softens the flavour when stirred in at the end.
The step that matters
Pulping the vegetables through a coarse sieve. Pressing the cooked vegetables through the sieve breaks down their cell walls, which thickens the soup and gives it a smooth body. Vegetables that are not fully tender will not pulp easily and can leave a grainy texture.
Swap the onion
How well each one fits the dish's main ingredients (parsnip, celery, pepper, milk):

- Onionthe original
Fit is the average pairing score against parsnip, celery, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
