Boiled Cod
Ingredients
Directions
Prepare
Place the cod in cold water with a handful of coarse sea salt and let it soak for one hour.
Scrape and wash the fish clean, then rub a little salt and cayenne pepper into the body.
Cook and serve
Dust a cloth with flour, wrap the fish tightly, and place it in boiling water.
Once boiling, cook for thirty minutes or until done, depending on the size of the fish.
Serve with drawn butter and chopped hard boiled eggs, or with oyster sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Provides the main body of the dish, cooked gently in boiling water until it flakes.
- Hard boiled eggs
- Add soft, rich texture and a mild savoury flavour to the finished dish.
- Drawn butter
- Adds fat and richness, moistening the mild cooked fish.
The step that matters
Cooking the wrapped fish in boiling water. Fish proteins toughen and dry out if overcooked, so the fish should be checked for doneness at the stated time, since size changes how long it takes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
