Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turtle
- Provides the main body of meat and the rich, gelatinous character of the soup.
- Brown flour
- Thickens the soup as its starch swells and gelatinizes when heated with liquid.
- Sherry or madeira wine
- Adds acidity and aromatic depth to the finished soup.
- Hard-boiled egg yolks
- Enrich the soup with a creamy texture and richness.
- Bread crumbs
- Bind the chopped meat so it holds its shape in the cakes.
- Butter
- Browns the cakes in the pan and adds fat and flavour.
The step that matters
Thickening with brown flour. Flour must be mixed with some hot soup first and stirred constantly until it boils, so the starch swells evenly; added dry or left unstirred, it forms lumps and the soup stays thin or grainy.
Swap the allspice
How well each one fits the dish's main ingredients (ham, pepper, lemon, egg, bread, butter, sherry):
- Parsleyfits better
- Thymefits better
- Marjoramfits better
- Allspicethe original
Fit is the average pairing score against ham, pepper, lemon, egg, bread, butter, sherry. Candidates are from the same food group and used in at least 100 recipes.
