Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken or knuckle of veal
- Gives the broth savory flavour and body as it simmers.
- Peas
- Their starch thickens the soup as they cook and break down.
- Cream
- Adds richness and a smooth, velvety mouthfeel to the soup.
- Butter
- Adds fat that carries flavour and rounds out the seasoning.
The step that matters
Add a handful of peas and boil to thicken the soup. Peas are starchy, so boiling them until they soften releases starch that thickens the broth. Stopping too early leaves the soup thin, while boiling too hard can make it gluey or dull in colour.
Swap the peas
How well each one fits the dish's main ingredients (chicken, pepper, cream, butter):
- Peanutfits better
- Beansfits better
- Cashew nutfits better
- Peasthe original
Fit is the average pairing score against chicken, pepper, cream, butter. Candidates are from the same food group and used in at least 100 recipes.
