Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vegetable marrow
- Forms the body of the soup, becoming tender and soft as it cooks and breaks down.
- Butter
- Adds richness and carries flavor as it softens the onion.
- Onion
- Builds a sweet, mellow aromatic base as it cooks slowly until soft.
- Veal stock or broth
- Supplies the liquid and savory depth that gives the soup its body.
- Milk
- Adds creaminess and softens the soup's texture.
- Cream
- Adds fat for a smooth, silky mouthfeel and a rounder finish.
The step that matters
Pressing through a fine sieve. Pressing the cooked marrow and onion through a fine sieve removes fibers and lumps, giving a smooth texture. Adding dairy after straining keeps it from curdling during cooking.
Swap the onion
How well each one fits the dish's main ingredients (butter, veal, milk, cream, pepper):
- Potatofits better
- Capsicumfits about as well
- Onionthe original
- Leekfits about as well
Fit is the average pairing score against butter, veal, milk, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
