Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Forms the main body of the stew and flakes into tender pieces as it cooks.
- Butter
- Adds fat for frying and helps the fish and onions take on golden browning.
- Flour
- Thickens the cooking liquid into a light sauce as it simmers.
- Red wine
- Adds acidity and depth of flavour to the sauce as it reduces.
- Mushrooms
- Contribute savoury, earthy flavour and soft texture to the sauce.
The step that matters
Fry until golden brown. Browning the fish and onions in butter builds flavour through the Maillard reaction. Fish cooked too long or over high heat can break apart and toughen, so brown gently and avoid overcrowding the pan.
