Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal
- Long slow simmering draws gelatin from the meat, giving the broth body and a rich mouthfeel.
- Beef bones
- Release gelatin and marrow flavour during long cooking, adding body and depth to the broth.
- Sweetbreads
- Their delicate, tender texture and mild richness become the soft, luxurious element of the soup.
- Tapioca
- Starch that thickens the broth slightly, giving it a smoother body.
- Corned ham
- Adds salty, savoury flavour that seasons the broth from within.
- Onion
- Contributes aromatic sweetness and savoury depth to the stock.
The step that matters
Cook slowly for 4 hours. Gentle, sustained simmering extracts gelatin and flavour from the bones and meat without boiling hard, which would emulsify fats and cloud the broth.
