Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Unclarified stock
- Forms the liquid base that carries the flavour of the whole soup.
- Egg white
- Coagulates as it heats, collecting fine particles so the stock can be clarified.
- Beef gravy
- Adds savoury depth and body to the stock.
- Green peas
- Contribute sweetness and fresh vegetable flavour and texture.
- Asparagus tops
- Add a delicate, slightly grassy flavour and tender texture.
The step that matters
Whisk until it boils, then simmer. Whisking while the egg white heats lets it coagulate and trap cloudy particles. Boiling too hard or stirring afterwards breaks up the raft, leaving the soup murky.
Swap the onion
How well each one fits the dish's main ingredients (peas, beans, asparagus, lettuce, carrot, beef, egg):
- Leekfits better
- Spinachfits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against peas, beans, asparagus, lettuce, carrot, beef, egg. Candidates are from the same food group and used in at least 100 recipes.
