Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Forms the body and main vegetable flavour of the soup as it simmers and softens.
- Butter
- Adds richness and carries flavour when it melts and cooks the celery gently.
- Milk
- Adds creaminess and a mild, smooth body to the finished soup.
- Crushed tapioca
- Thickens the soup as its starch swells and gelatinises during simmering.
- Marmite
- Adds savoury depth and a salty, umami note to the broth.
The step that matters
Simmering the tapioca. Tapioca thickens only as its starch swells and cooks through during sustained simmering. Stirring it in and boiling for the full 30 minutes prevents lumps and a raw, pasty taste.
Swap the celery
How well each one fits the dish's main ingredients (butter, milk, cream):
- Nutmegfits better
- Cinnamonfits better
- Macefits about as well
- Celerythe original
Fit is the average pairing score against butter, milk, cream. Candidates are from the same food group and used in at least 100 recipes.
