Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod fillets
- Forms the main body of the dish and cooks to a flaky texture.
- Butter
- Adds fat for richness and a silky mouthfeel as it coats the fish.
- Mustard
- Adds a sharp, tangy flavour that balances the richness of the butter.
The step that matters
Broil the fillets until golden brown.. Cod is lean and thin fillets cook fast under direct high heat. Browning and drying happen quickly, so the fish can turn dry and tough if left too long. Check it often and remove it as soon as it is opaque and flakes easily.
