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 ↓

Ingredients
Directions
Make the tomato base
Combine the tomatoes, brown stock, bay leaf, parsley, celery, and sugar in a saucepan and simmer thoroughly.
Make the onion roux
Melt the butter in a sauté pan and add the onion, cooking until the onion is soft but not browned.
Stir in the flour and mix well.
Combine and finish
Combine the onion mixture with the tomatoes and season with salt and pepper.
Pass the mixture through a fine sieve or strainer.
Heat again and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Canned tomatoes
- Provide the main body and flavor of the puree.
- Brown stock
- Adds liquid and savory depth to the tomato base.
- Butter
- Adds fat and richness to the onion mixture.
- Flour
- Thickens the mixture as it cooks with the butter and onion.
- Sugar
- Balances the acidity of the tomatoes with a touch of sweetness.
The step that matters
Cook the onion until soft but not browned. Browning the onion adds dark, bitter notes and changes the color and flavor of the puree. Gentle cooking softens the onion so it blends smoothly into the tomatoes.
