Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oxtail
- Provides the meat, bones and gelatin that give the soup its body and flavour.
- Butter
- Carries flavour and enriches the soup as the base of the roux.
- Flour
- Thickens the soup with the butter as a roux, giving it body.
- Red currant jelly
- Adds sweetness and fruity acidity that balances the rich meat.
- Madeira
- Adds aromatic sweetness and depth to the finished soup.
The step that matters
Bring the puree to a boil until thickened. Flour thickens only when its starch is heated enough to swell and set. Boiling the puree fully ensures the soup thickens evenly, while stirring prevents lumps and scorching on the base of the pan.
Swap the red currant
How well each one fits the dish's main ingredients (butter, flour, anchovy, vinegar, pepper):
- Lemonfits better
- Limefits better
- Cherryfits better
- Red currantthe original
Fit is the average pairing score against butter, flour, anchovy, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
