Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef shank
- Gives the broth its meaty flavour and, through long simmering, a fuller body.
- Peas or beans
- Softened during cooking, they release starch and flavour into the liquid.
- Onions
- Add savoury depth and aroma when seasoned into the finished broth.
The step that matters
Cook the peas or beans until soft. Beans must be fully softened before straining so their starch and flavour pass into the liquid. Undercooked legumes stay firm, hold their starch, and leave the broth thin and less flavourful.
Swap the peas
How well each one fits the dish's main ingredients (beef, onion, pepper):
- Sesamefits better
- Black-eyed peafits better
- Beansfits better
- Peasthe original
Fit is the average pairing score against beef, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
