Directions
Make the soup base

Mix flour with a little butter until smooth, then add to the onions and let fry.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Browning in butter builds the deep, sweet flavour of the soup base.
- Flour
- Thickens the soup as it fries with the butter and onions.
- Turnip
- Adds body and a mild, earthy sweetness as it becomes tender.
- Carrot
- Adds sweetness and soft texture once boiled until tender.
- Celery
- Adds savoury, aromatic flavour and soft texture once boiled.
The step that matters
Frying the flour with butter. Flour must be cooked in fat until smooth and fully mixed before it goes into the soup. Adding it lumpy or undercooked leaves a pasty taste and uneven thickness, because raw starch does not thicken well until it is hydrated and heated.
Swap the mace
How well each one fits the dish's main ingredients (onion, butter, pepper, flour, turnip, carrot, celery):
- Parsleyfits better
- Thymefits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against onion, butter, pepper, flour, turnip, carrot, celery. Candidates are from the same food group and used in at least 100 recipes.
