Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Provides the main body and the green flavour of the soup.
- Egg yolk
- Thickens the soup and adds richness when gently heated.
- Heavy cream
- Adds fat for a smoother, silkier texture and mellows the flavour.
- Chicken stock
- Supplies the liquid base and savoury depth for the soup.
The step that matters
Adding the egg yolk after reheating. Egg yolk thickens by gently coagulating its proteins. If the soup is too hot when the yolk goes in, it can curdle and turn grainy, so it should be added off the heat or at a low temperature.
