Why it works: Celery and leek match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,093 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Celery Cream Soup
Ingredients
Directions
Prepare
Remove the root end from the leeks and slice the white part, placing it in a clean saucepan.
Remove the root from the celery and cut the inner stalks into shreds.
Make the soup
Add the celery, leeks, ham, butter, a pinch of salt, a few white peppercorns, and a bit of mace to the pan.
Cook without browning for 15 minutes, then add the stock and skim the surface.
Simmer for about 1.5 hours, then pass through a fine sieve back into the pan.
Finish and serve
Blend the potato flour with a little cold milk and add it 10 minutes before serving.
Heat the milk and cream separately, mix with the puree, and serve with diced croutons.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Forms the main body of the soup and gives it its characteristic flavour.
- Leeks
- Add a mild onion-like sweetness and savoury depth to the base.
- Butter
- Adds richness and carries flavour during the initial gentle cooking.
- Potato flour
- Thickens the soup to a smooth, velvety body.
- Cream
- Adds fat and a silky, rounded texture to the finished soup.
- Stock
- Provides the liquid base and savoury backbone of the soup.
The step that matters
Cook without browning. Gentle cooking without browning keeps the celery and leeks sweet and pale, so the soup stays delicate in flavour and colour. Browning would add bitter, roasted notes that dominate the cream soup.
Swap the celery

- Nutmegfits better
- Capersfits about as well

Fit is the average pairing score against leek, potato, flour, butter, ham, milk, cream. Candidates are from the same food group and used in at least 100 recipes.
