Why it works: Celery and turnip are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,418 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Tapioca Cream Soup
Ingredients
Directions
Make the stock
Boil the celery, onion, and turnip in the water for 1 hour.
Strain the vegetables and boil the tapioca in the strained liquid until clear and thick.
Finish the soup
Beat the egg yolk and mix in the cream.
Pour the boiling stock into the egg and cream mixture, stirring well.
Season with salt and pepper.
If the tapioca rises to the top, the egg is cooked enough.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- French tapioca
- Swells as it boils, thickening the liquid and turning it clear.
- Egg yolk
- Enriches and thickens the soup when stirred into the hot stock and cream.
- Cream
- Adds richness and a smooth, silky texture.
- Turnip
- Contributes flavour and body to the vegetable stock.
The step that matters
Pour the boiling stock into the egg and cream mixture, stirring well. Stirring keeps the hot liquid moving so the egg yolk warms gradually and blends in smoothly. Pouring it in all at once or without stirring can scramble the yolk and leave lumps instead of a creamy soup.
Swap the onion
How well each one fits the dish's main ingredients (egg, cream, celery, turnip, pepper):
- Leekfits better
- Spinachfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against egg, cream, celery, turnip, pepper. Candidates are from the same food group and used in at least 100 recipes.
