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

What each ingredient does

Butter
Fat that softens the vegetables gently and carries flavour without browning them.
Onion
Aromatic base that sweetens as it cooks and builds the soup's savoury flavour.
Carrots
Add natural sweetness and body to the soup as they soften.
Turnip
Adds mild, slightly peppery flavour and body as it becomes tender.

The step that matters

Cook the vegetables for 10 minutes without browning. Gentle cooking in butter softens the vegetables and draws out their sweetness. Browning would add bitter, toasted flavours that change the clear, delicate character of the soup.
