Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Provides the main flavor and, once pressed through a sieve, the body of the soup.
- Cream sauce
- Supplies richness and a smooth, creamy texture to the soup.
- Water or white stock
- Cooks the asparagus and thins the soup to a pourable consistency.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (asparagus, cream, sauce, parsley):
- Shallotfits better
- Spinachfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against asparagus, cream, sauce, parsley. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
