Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Split peas
- Thicken the soup and give it body as they break down during boiling.
- Potatoes
- Break down during boiling to add starch that thickens and smooths the soup.
- Cream
- Adds richness and a silky mouthfeel to the finished soup.
- Milk
- Adds softness and creaminess, mellowing the flavour of the soup.
The step that matters
Boil until smooth. The soup must cook long enough for the split peas, potatoes and vegetables to soften fully. Under-cooked solids will not break down, leaving the sieved texture grainy rather than smooth.
Swap the peas
