Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Chicken: Slow cooking in broth makes the meat tender and gives the soup its savory body.
Chicken broth: Provides the liquid base that carries the flavor of the other ingredients.
Noodles: Absorb liquid as they cook, providing the soup's main starch and body.
Carrots: Add sweetness and color as they soften during the long cook.
Celery: Adds savory aroma and a tender, slightly crisp texture after cooking.
Onion: Releases sugars and aroma as it cooks, building the soup's flavor base.

The step that matters

Adding the noodles. Noodles cook quickly in hot liquid and keep absorbing broth, so they can turn mushy or soak up the soup if left too long. Check them near the end of the 30 minutes and add more broth if the soup thickens too much.
