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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Break down into a pulp that forms the body and thickness of the soup.
- Butter
- Melts to carry flavor and give the soup a rich, smooth mouthfeel.
- Onion
- Softens during stewing to add savory sweetness and aromatic depth.
- Celery
- Softens during stewing to add a mild, vegetal aroma and savory base.
- Anchovies
- Dissolve into the butter to add savory depth without a distinctly fishy taste.
- White sugar
- Added at the end to balance savory notes with a touch of sweetness.
The step that matters
Add the pea pulp until the soup reaches the desired thickness.. Pea pulp thickens as it is added and only partly sets, so adding too much makes the soup pasty. Add it gradually and judge the consistency as you go, since the soup thickens further once boiled.
Swap the onion
How well each one fits the dish's main ingredients (peas, butter, celery, pepper, mint, parsley, spinach):

Fit is the average pairing score against peas, butter, celery, pepper, mint, parsley, spinach. Candidates are from the same food group and used in at least 100 recipes.
