Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down during simmering to give the soup body and a thicker texture.
- Onions
- Build savory sweetness and depth as they soften in the pot.
- Celery
- Adds aromatic, savory flavor to the base as it cooks gently.
- Carrot
- Contributes natural sweetness and color to the finished soup.
- Broth
- Forms the liquid base that carries and blends the vegetable flavors.
The step that matters
Cover tightly and cook gently. Gentle heat under a tight lid softens the vegetables and draws out their flavor without boiling away liquid or scorching. A hard boil would make the soup cloudy and reduce its volume.
Swap the onion
How well each one fits the dish's main ingredients (potato, turnip, celery, carrot, pepper):
