Serve
Pour the soup into a tureen and lay the poached eggs neatly on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ham bone
- Releases flavour and gelatin into the water as it simmers, giving the stock its body.
- Rice
- Absorbs liquid and softens as it simmers, thickening the soup slightly.
- Poached eggs
- Add richness and substance as a topping that enriches each bowl.
The step that matters
Simmer until the rice is soft, skimming often. Rice keeps absorbing liquid and can turn mushy if overcooked. Skimming removes foam and fat that would otherwise cloud the broth and taste greasy.
