Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown flour
- Thickens the soup as it cooks, giving it body.
- Butter
- Adds richness and fat that carries the flavour of the aromatics.
- Hard-boiled egg yolks
- Add richness and a smooth, thickened texture to the soup.
- Turtle
- Provides the main meat and character of the soup.
The step that matters
Mix the brown flour into a paste before stirring it into the soup. Flour added dry clumps and stays lumpy. Mixing it first with a little water lets the starch disperse evenly, so it thickens the soup smoothly when heated.
Swap the onion
How well each one fits the dish's main ingredients (beef, flour, butter, parsley, carrot, ham, egg):
- Leekfits better
- Shallotfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against beef, flour, butter, parsley, carrot, ham, egg. Candidates are from the same food group and used in at least 100 recipes.
