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 ↓
Sauce for Salmon Loaf
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.
Melt the butter in a saucepan over medium heat.
Stir in the flour and cook for 1-2 minutes.
Gradually add the hot milk, stirring constantly until creamy.
Remove from heat and mix in the salmon juice and beaten egg.
Season with salt, pepper, and lemon juice to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and flavour to the base of the sauce.
- Flour
- Thickens the sauce when cooked briefly with the butter.
- Milk
- Forms the liquid body of the sauce, which thickens as it heats.
- Egg
- Adds richness and gently thickens the sauce when stirred in off the heat.
The step that matters
Adding the hot milk to the roux. Adding the liquid gradually while stirring constantly keeps the flour dispersed, so the sauce becomes smooth and creamy rather than lumpy.
