Why it works: Celery and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,810 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

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):
