Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal knuckle
- Gives the soup a rich, savoury body as it simmers into the stock.
- Lean ham or bacon
- Adds savoury, smoky flavour to the stock.
- Arrowroot
- Thickens the soup into a smooth, silky texture without making it cloudy.
- Cream
- Adds fat for a richer mouthfeel and a softer, creamier finish.
- New milk
- Adds creaminess and mild sweetness, softening the soup's flavour.
The step that matters
Blending the arrowroot with cream before adding it. Arrowroot clumps if added dry or straight into hot liquid. Mixing it smoothly with cold cream first lets it disperse evenly, so it thickens the soup without lumps.
