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 dish and firms up as it cooks.
- Butter
- Adds richness and helps brown the cod surface when fried.
- Egg-sized piece of butter, rolled in flour
- Flour-coated butter melts into the liquid and thickens it into a smooth sauce.
- Oysters
- Contribute a briny, savoury flavour to the sauce.
- Lemon juice
- Adds acidity that brightens the rich, buttery sauce.
The step that matters
Cook until the fish is done. Cod turns opaque and flaky when cooked through but becomes dry and tough if overcooked. Because it was only half cooked earlier, the final simmer needs careful timing to finish it gently.
Swap the onion
How well each one fits the dish's main ingredients (butter, wine, nutmeg, pepper, egg, flour, mushroom):
- Shallotfits better
- Spinachfits better
- Chivefits better
- Onionthe original
