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 ↓

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.
In a saucepan, melt the butter over medium heat.
Stir in the flour and cook for 1 minute.
Gradually add the milk, stirring until smooth.
Season with pepper and salt to taste.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and fat, carrying flavor and giving the sauce a smooth mouthfeel.
- Flour
- Thickens the milk into a sauce when cooked briefly with the melted butter.
- Milk
- Forms the liquid base of the sauce, which thickens as the starch swells with heat.
The step that matters
Adding the milk. If milk is added too fast or the roux is too hot, lumps form because the starch clumps before it can disperse. Adding the milk gradually while stirring keeps the sauce smooth.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
