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
Prepare the vegetables
Wash the celery thoroughly and cut it into 1-inch lengths.
Put the celery and onion into a pan with just enough water to cover them and stew gently for 2 hours, or until very tender.
Rub the mixture through a fine sieve to remove any solids.
Make the soup
Put the puree into a pan with the stock, milk, bay leaf, mace, and salt and pepper to taste.
Mix the cornflour with a little cold water.
Just before the soup boils, add the mixture to the pan.
Stir continuously until the soup thickens, then simmer for 5 minutes.
Serve
Serve with slices of fried bread.
For a richer soup, stir in ½ pint of whipped cream just before serving.

Pepper and mace barely smell alike, yet cooks put them together in 12,257 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, once stewed and sieved, the body of the soup.
- Milk
- Adds creaminess and softens the flavour of the stock.
- Cornflour
- Thickens the soup when stirred into liquid and heated until it sets.
- Spanish onion
- Adds savoury sweetness as it softens during the long stew.
The step that matters
Adding the cornflour mixture. Cornflour must be dispersed in cold water first and added near boiling, then stirred constantly. Added to hot liquid without this, it clumps, and the soup thickens unevenly.
Swap the mace
How well each one fits the dish's main ingredients (celery, milk, onion, pepper):
- Parsleyfits better
- Thymefits better
- Turmericfits better
- Macethe original
Fit is the average pairing score against celery, milk, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
