Why it works: Parsley and celery 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 ↓
Tomato Sauce
Ingredients
Directions
Combine the stewed tomatoes, onion, parsley, celery, bay leaf, and mace in a saucepan.
Simmer slowly for 10 minutes.
In a separate hot saucepan, melt the butter and flour together until smooth.
Strain the tomato mixture into the saucepan through a sieve.
Stir constantly until it boils.
Season with salt and pepper to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stewed tomatoes
- Provide the main body and tomato flavour of the sauce.
- Butter and flour
- Melt together to form a roux that thickens the sauce.
The step that matters
Stir constantly until it boils. Flour thickens liquid only as its starch swells with heat and is dispersed evenly. Stirring prevents lumps and scorching on the bottom of the pan.
Swap the mace
How well each one fits the dish's main ingredients (tomato, onion, parsley, celery, butter, flour, pepper):
- Thymefits better
- Tarragonfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against tomato, onion, parsley, celery, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
