Why it works: Milk and egg are a kitchen classic. They rank in the top 9% of all ingredient pairs, and 88,465 recipes mention both. Both carry 2-nonenal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: egg, milk, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare
Soak the salted cod in cold water overnight.
Scrape off the dark skin with a cloth and wash thoroughly.
Cook

Boil gently until tender, about 45 minutes, removing scum as it rises.
Serve
Serve on a hot napkin with egg sauce.

What each ingredient does
- Salted cod
- Main protein that turns firm and flaky as it cooks in the liquid.
- Milk
- Mellows the salty flavour of the cod and keeps the flesh soft and moist.
The step that matters
Boil gently, not hard. A hard boil breaks the delicate fish into pieces and toughens the proteins. Gentle heat cooks the cod evenly, and skimming the scum as it rises keeps the liquid clear.
