Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Old green peas
- Main body of the soup, thickened into a purée when mashed and rubbed through a cloth.
- Onions
- Build the aromatic flavour base of the broth during the long stew.
- Turnips
- Add body and savoury sweetness to the broth as they stew.
- Cabbage lettuces
- Contribute vegetable flavour and body to the stewed broth.
- Celery
- Adds aromatic, savoury flavour to the broth.
- Carrots
- Add gentle sweetness and flavour to the broth.
The step that matters
Rubbing the mixture through a cloth. Pushing the mashed peas through a cloth removes skins and fibres, giving a smooth texture. Skipping or rushing this leaves the soup grainy.
Swap the mace
How well each one fits the dish's main ingredients (onion, turnip, carrot, celery, clove, cabbage, lettuce):
- Parsleyfits better
- Thymefits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against onion, turnip, carrot, celery, clove, cabbage, lettuce. Candidates are from the same food group and used in at least 100 recipes.
