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.
