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

What each ingredient does

Stale wholemeal bread crusts
Soaked and sieved, they thicken the soup and give it a smooth body.
Onions
Slow simmering softens them and releases sweetness that rounds out the broth.
Turnips
They soften during simmering and add a mild, slightly peppery sweetness.
Butter
Adds richness and a silky mouthfeel to the finished soup.
Milk
Stirred in near the end, it adds creaminess and softens the flavour.

The step that matters

Bringing the soup back to a boil after adding the milk. Milk can scorch on the base of the pan or separate when it gets too hot. Heating it gently and watching the pot closely keeps the soup smooth and prevents a burnt taste.

Swap the onion

How well each one fits the dish's main ingredients (bread, turnip, celery, butter, parsley, milk, pepper):

  1. Carrotfits better
  2. Leekfits better
  3. Parsnipfits better
