Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arrowroot
- Thickens the soup into a smooth, velvety body as it heats.
- Cream
- Adds richness and a silky mouthfeel to the finished soup.
- New milk
- Adds moisture and mild sweetness, making the soup creamy and pale.
- Veal knuckle
- Releases gelatin and savory flavor into the water during long simmering.
- Ham or bacon
- Contributes salty, smoky depth to the broth.
The step that matters
Stirring the arrowroot mixture into the soup. Arrowroot must be blended smoothly with cream first and then stirred in while the soup is hot. Added as lumps or left unstirred, it clumps instead of thickening evenly, and simmering afterward keeps the starch-thickened body uniform.
