Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Gives the broth its meaty flavour and body as it simmers until tender.
- Peas
- Their pulp thickens the soup and gives it body and a mild sweetness.
- Butter
- Adds richness and fat, carrying flavour and giving the greens a silky texture.
- Cream
- Adds richness and creaminess and lightens the colour to the white the soup is meant to be.
- Cabbage lettuces
- Cooked slowly in butter, they soften and add body and a gentle vegetable sweetness.
The step that matters
Pour in the remaining soup and enough cream to achieve a white color.. Adding cream to a boiling soup can cause it to curdle or separate. Adding enough cream for a white colour needs care, and stirring until just boiling keeps the emulsion smooth.
