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
- Potatoes
- Break down while simmering to give the soup body and a thicker texture.
- Flour
- Thickens the soup slightly when cooked with butter, adding body.
- Butter
- Adds richness and carries flavor, and pairs with flour to form the thickening base.
