Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Their yolks are crushed into the broth, adding body and a rich, mellow flavour.
- Raw egg yolks
- They thicken the soup as they gently set, giving it a smooth, creamy texture.
- Oysters
- They contribute their briny, savoury flavour to the broth and become tender during simmering.
- Fish stock
- It forms the liquid base of the soup and carries the flavour of the other ingredients.
The step that matters
Stir gently until thick and smooth, without boiling. Raw egg yolks thicken by gentle heat. If the soup boils, the yolks can scramble into curds, leaving the soup grainy instead of smooth.
