Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Celery Soup
Ingredients
Directions
Make the soup
In a pot, combine chopped celery, white stock, diced ham, and butter.
Simmer gently for 1 hour.
Strain the mixture through a sieve, returning the liquid to the pot.
Finish and serve
If desired, thicken with a little flour.
Carefully stir in a few spoonfuls of cream.
Serve with toasted bread and season to taste.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides the main flavour and most of the body of the soup.
- White stock
- Forms the liquid base that the celery softens and flavours in.
- Lean ham
- Adds savoury, meaty flavour to the broth.
- Butter
- Adds richness and a smooth mouthfeel to the soup.
- Cream
- Adds richness and a smoother, mellower texture when stirred in at the end.
- Flour
- Thickens the liquid slightly if used.
The step that matters
Carefully stir in a few spoonfuls of cream. Cream can curdle or separate if it boils after being added to a hot, acidic or salty liquid. Stirring it in gently and keeping the soup below a boil keeps it smooth.
Swap the celery

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