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 ↓
Tomato Puree
Ingredients
Directions
Make the tomato base
Combine tomatoes, brown stock, bay leaf, parsley, celery, and sugar in a saucepan and simmer thoroughly.
Melt butter in a sauté pan, add onions, and cook until soft but not browned.
Thicken and finish
Stir in flour and mix well, then add this mixture to the tomatoes.
Season with salt and pepper, pass the mixture through a fine sieve, and heat again.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and tomato flavour of the puree.
- Butter
- Adds fat and richness while softening the onions without browning them.
- Flour
- Thickens the liquid so the puree becomes smooth and body-rich.
- Brown stock
- Adds savoury depth and liquid to the tomato base.
- Onion
- Contributes savoury aroma and sweetness as it softens gently.
The step that matters
Cooking the onions until soft but not browned. Browning changes the flavour toward bitter and caramelised notes that would alter the clean tomato taste. Gentle cooking in butter softens the onions so they blend smoothly and keep the puree's colour and flavour light.
Swap the onion
