Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soaked cod
- Provides the main protein and flaky body of the stew.
- Butter
- Adds richness and fat that carries flavour through the stew.
- Flour
- Thickens the liquid so the stew holds together rather than running thin.
- Milk
- Moistens the mixture and forms the creamy liquid of the stew.
The step that matters
Add enough milk to moisten the mixture. Flour thickens only when it is evenly hydrated with liquid. Adding too little milk leaves dry, pasty lumps, while adding it gradually keeps the flour smooth and the texture even.
