Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Creamed Codfish
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the sauce
In a saucepan, melt the butter over medium heat.
Stir in the flour and cook for 1-2 minutes until smooth.
Gradually add the milk, stirring constantly until the mixture thickens.
Finish and serve
Add the flaked codfish, lemon juice, salt, and pepper.
Cook until heated through, then stir in the beaten egg.
Serve hot over toast.

Flour and butter 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
- Milk
- Forms the liquid base that thickens into a smooth, creamy sauce.
- Flour
- Thickens the butter and milk into a smooth sauce as it cooks.
- Butter
- Carries the flour and adds richness to the sauce.
- Egg
- Enriches and thickens the sauce when stirred in at the end.
- Codfish
- Provides the main protein and flavor of the dish.
The step that matters
Stir in the beaten egg after the codfish is heated. Egg proteins set when heated, so adding it to a boiling or very hot sauce can scramble it. Heat it gently until just hot through and stir steadily.
