Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salted fish
- Provides the main protein and a seasoned, firm flesh that holds up during simmering.
- Curry powder
- Supplies the spice base that flavours the water and the whole stew.
- Butter
- Carries the aromatics and adds richness and browning to the onion mixture.
- Onions
- Browned in butter, they add sweetness and body to the sauce.
- Shallot
- Adds a mild, sharp aromatic note that deepens the sautéed base.
The step that matters
Simmering the fish until tender. Simmering gently keeps the fish moist and intact; a hard boil toughens proteins and breaks the flesh apart. Salted fish also needs to be tender before the onion mixture is added, so the texture is set at this stage.
