Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the soup and helps the onions brown when dredged and stirred.
- Butter
- Adds richness and fat for frying the onions and for the flour thickener.
- Onions
- Browned in butter, they add sweetness and deep savory color to the soup.
- Neck of beef
- Releases flavor and gelatin into the stock during long simmering.
The step that matters
Stirring the flour and butter into the soup. Added raw, flour clumps and tastes pasty; mixing it with butter first and stirring it into hot liquid lets the starch disperse and thicken evenly.
