Ingredients
Directions
In a stew-pan, melt the butter and add the onions and celery.

Stir in 2 quarts of stock and the crumb of the French rolls; boil for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Softened in butter, they build the sweet, savoury base of the soup.
- Celery
- Softened with the onions, it adds aromatic flavour to the soup base.
- Carrots
- Simmered until tender, they give the soup its main body and colour.
- French rolls
- Their crumb thickens the soup as it boils.
The step that matters
Rub the mixture through a fine sieve and keep the soup hot without boiling. Pressing the cooked vegetables and crumb through a fine sieve breaks them down into a smooth texture. Keeping the soup below a boil avoids scorching and prevents it from thickening further or separating.
Swap the onion
How well each one fits the dish's main ingredients (butter, celery, carrot):
- Parsnipfits better
- Leekfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against butter, celery, carrot. Candidates are from the same food group and used in at least 100 recipes.
