Chef's tips
Dried dulse contains natural sea salts, so taste the melted herb butter before adding any extra table salt. Use thick loin cuts of cod to ensure even cooking without drying out.
Ingredient substitutions
- cod fillets → haddock or hake fillets
- unsalted butter → plant-based block butter for a dairy-free version
- dried dulse → dried nori or sea lettuce flakes
Storage
Store leftover baked cod in an airtight container in the fridge for up to two days.
Reheating
Reheat gently in an ovenproof dish covered with foil at 160°C until piping hot throughout.
Common mistakes to avoid
- •Over-salting the dish without accounting for the natural salinity of dried dulse
- •Overbaking the fish until the cod turns dry and rubbery
- •Leaving the dulse pieces too large, which makes them chewy rather than melting into the butter
