Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Provides the main flavour and, when strained through the sieve, the body of the soup.
- Butter
- Carries the onion's flavour and, blended with flour, enriches and thickens the soup.
- Flour
- Thickens the soup when cooked with butter, giving it a smoother body.
- Cream
- Adds richness and a smooth, velvety texture to the finished soup.
- Onion
- Adds savoury depth when fried gently in butter before simmering.
The step that matters
Blending butter and flour into the soup. Flour must be fully blended with butter and cooked slowly, stirring, so it thickens smoothly without lumps or a raw floury taste.
Swap the onion
How well each one fits the dish's main ingredients (asparagus, butter, flour, cream, parsley, pepper, celery):
- Leekfits better
- Spinachfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against asparagus, butter, flour, cream, parsley, pepper, celery. Candidates are from the same food group and used in at least 100 recipes.
