Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Fish
Ingredients
Directions
Prepare the fish
Wash the fish and tear it into bits. Soak it in cold water overnight.
In the morning, drain the water and place the fish in a frying pan. Add enough fresh cold water to cover it.
Bring the water to a boil, then reduce the heat and simmer for 15 minutes until the fish is cooked.
Drain the fish well.
Make the milk sauce
Place the fish in a double boiler with the milk, or carefully pour the milk over the fish in the pan while stirring constantly to prevent scorching.
Once the milk is boiling, stir in the flour and butter (or wet corn-starch with a little cold milk).
Cook slowly for 5 minutes.
Season with pepper and salt if needed.
Finish and serve
Remove from heat.
Stir in the beaten egg mixed with 1 tablespoon of milk.
Let it stand for 2 minutes.
Serve on a hot platter.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish and becomes tender when simmered and cooked through.
- Milk
- Provides the liquid base of the sauce and carries the dish's creamy texture.
- Egg
- Enriches the sauce and thickens it gently when stirred in off the heat.
- Flour or corn-starch
- Thickens the milk into a smooth sauce as it heats.
- Butter
- Adds richness and a silky mouthfeel to the sauce.
The step that matters
Stirring in the egg off the heat. Egg proteins set when heated, so adding the beaten egg to a boiling sauce can scramble it into lumps. Removing the pan from heat first lets the egg thicken the sauce gently and evenly.
