Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tails
- Provide meat and gelatin that enrich the broth as they cook.
- Butter
- Fat for frying the vegetables, carrying flavour and aiding browning.
- Browned flour
- Thickens the soup and adds a toasted, nutty flavour.
- Onions
- Build savoury sweetness and aroma as they soften in fat.
- Bacon
- Adds smoky, salty fat and savoury depth to the vegetables.
- Sherry
- Adds acidity and aromatic complexity to the finished soup.
The step that matters
Strain the mixture. Straining removes the cooked vegetable solids and bits so the soup is smooth and clear. Thickening from browned flour needs even mixing, so the flour should be fully incorporated before boiling again.
Swap the onion
How well each one fits the dish's main ingredients (butter, turnip, carrot, celery, beef, flour, sauce):
- Leekfits better
- Parsnipfits better
- Shallotfits about as well
- Onionthe original
Fit is the average pairing score against butter, turnip, carrot, celery, beef, flour, sauce. Candidates are from the same food group and used in at least 100 recipes.
