Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Split peas
- Provide the main body and starch that thicken the soup as they cook and break down.
- Milk
- Adds creaminess and a softer, smoother texture to the mashed peas.
- Butter
- Adds fat for richness and a smooth, rounded mouthfeel.
The step that matters
Boil the mixture once. Milk-based soups can scorch on the bottom of the pan or separate and curdle if they are boiled hard, so the mixture should be brought up to a boil briefly and watched closely.
Swap the peas
How well each one fits the dish's main ingredients (milk, butter, pepper, bread):
- Lima beansfits about as well
- Cocoafits about as well
- Peasthe original
- Walnutfits about as well
Fit is the average pairing score against milk, butter, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
