Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish bones, trimmings, and skin
- Release gelatin and savoury flavour into the broth as they simmer.
- Milk
- Adds richness and a mild sweetness that softens the broth.
- Boiled rice
- Thickens the soup slightly and adds body.
The step that matters
Boil for 2 hours. A long, steady simmer extracts flavour and gelatin from bones and skin. A hard boil can cloud the broth and make it greasy, so keep it at a gentle simmer.
Swap the parsley
How well each one fits the dish's main ingredients (fish, rice, milk):
- Cinnamonfits better
- Turmericfits better
- Nutmegfits better
- Parsleythe original
Fit is the average pairing score against fish, rice, milk. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
