Why it works: Butter and milk 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 ↓
Creamed Codfish
Ingredients
Directions
Make the sauce
Heat 2 cups of milk in a double boiler, reserving ½ cup to mix with flour.
Make a paste with the reserved milk and 4 tablespoons of flour, then add it to the heated milk and cook.
Prepare the codfish
Soak 1 cup of codfish in cold water, then warm it slowly over low heat without letting it simmer.
If the fish is very salty, change the soaking water.
Combine and serve
Once the sauce is cooked, add it to the codfish and 2 tablespoons of butter.
If desired, stir in a beaten egg, cook for 1 minute, and serve.

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
- Flour
- Thickens the milk into a smooth sauce as its starch swells when heated.
- Milk
- Forms the liquid base of the sauce, giving it body and moisture.
- Codfish
- Provides the main flavor and texture of the dish.
- Butter
- Adds richness and a silky mouthfeel to the finished sauce.
- Egg
- Optionally enriches the sauce and thickens slightly when gently cooked.
The step that matters
Make a smooth paste before adding the flour mixture to the hot milk. Flour clumps if added dry or unmixed to liquid. Mixing it into a paste with a little cold milk first lets the starch disperse evenly, so when the sauce cooks it thickens smoothly instead of lumping.
