Why it works: Onion and thyme are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 11,171 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Clarify and serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hare
- Provides the main meaty flavour and body of the soup.
- Blood
- Helps clarify and thicken the stock as it cooks and is strained.
- Egg shells
- Their calcium-rich surface attracts particles, helping clarify the stock into a clear soup.
The step that matters
Clarify the soup. Egg shells and onion peels must be stirred in and then left to settle, so the particles bind and rise. Rushing this or stirring again leaves the soup cloudy instead of clear.
Swap the onion
How well each one fits the dish's main ingredients (thyme, egg, port wine):
- Shallotfits better
- Leekfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against thyme, egg, port wine. Candidates are from the same food group and used in at least 100 recipes.
