Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal
- Gives the broth savory depth and body as it simmers.
- Onions
- Add gentle sweetness and, once pressed through the sieve, body to the soup.
- Baker's loaf
- Its starch helps thicken the soup as the bread breaks down.
- Flour
- Its starch thickens the soup when cooked with butter and hot liquid.
- Butter
- Fat that combines with the flour to form a smooth thickening paste.
- Cream
- Adds richness and a silky texture to the finished soup.
The step that matters
Stirring the butter and flour into the boiling soup. Flour clumps if dropped in unmixed. Constant stirring spreads the starch evenly, and as it heats the starch swells and thickens the soup smoothly.
Swap the onion
