Why it works: Vinegar and horseradish are a kitchen classic. They rank in the top 6% of all ingredient pairs, and 2,588 recipes mention both. Both carry isobutyraldehyde, which smells malty, green. The science ↓
The recipe
Ingredients
Contains: fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: fish
Directions
Prepare
Rub coarse sea salt along the bone and thick part of the fish.
Tie the head with broad tape to prevent the cheeks from breaking.
Boil and check
Place the fish on a fish-plate and cover it completely with cold water.
Add a handful of salt, vinegar, and horseradish to the water.
Heat the water until it is just boiling and cook for about 30 minutes to 1 hour.
Check if the fish is done by lifting the fish-plate and testing if the meat separates easily from the backbone.

What each ingredient does
- Codfish
- Provides the main protein, which firms and flakes as it cooks in the hot water.
- Vinegar
- Adds acidity that brightens the mild flavour of the fish.
The step that matters
Heating the water to just boiling. Keeping the water at a gentle simmer rather than a hard rolling boil helps the flesh cook evenly and stay tender, while a violent boil can break the delicate cheeks and shoulders apart.
