Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides the main flavour and body of the soup once boiled and passed through a sieve.
- Chicken stock
- Supplies the savoury liquid base that carries the soup's flavour.
- Cream
- Adds richness and a smooth, velvety mouthfeel to the finished soup.
- Egg yolk
- Thickens the cream and enriches the soup when stirred in off the heat.
The step that matters
Stir in the cream and egg yolk off the heat. Egg yolk thickens by gentle heat and can scramble or curdle if the soup is boiling when it is added. Removing the pan from the heat first lets the yolk thicken the soup smoothly.
Swap the celery
How well each one fits the dish's main ingredients (onion, chicken, cream, egg):
- Garlicfits better
- Tarragonfits about as well
- Celerythe original
- Nutmegfits about as well
Fit is the average pairing score against onion, chicken, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
