Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the main body of the stew, becoming flaky and tender as it cooks.
- Butter
- Adds richness and browns the cod and onion for flavour.
- Wine
- Contributes acidity and aroma to the cooking liquid.
- Oysters
- Adds a briny, savoury flavour to the stew.
- Pickled mushrooms
- Adds tangy, savoury flavour that balances the richness of the butter.
The step that matters
Once the fish is done, pour in the cooking liquid from the stew.. Cod turns dry and tough if overcooked, so it should be removed from heat as soon as it flakes. Adding the flavourful liquid afterward keeps the fish moist and the broth well seasoned.
Swap the onion
How well each one fits the dish's main ingredients (butter, wine, nutmeg, pepper, egg, flour, mushroom):
