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 ↓
Cheese Soup
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 soup
In a saucepan, melt the butter over medium heat.
Stir in the flour and cook for 1 minute.
Gradually add the milk, stirring constantly until thickened.
Add the grated cheese, cayenne pepper, and salt, stirring until the cheese melts.
Remove from heat and stir in the beaten egg until well combined.
Serve
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and milk into a smooth, creamy base as it cooks.
- Milk
- Forms the liquid base that the flour thickens into a soup.
- Grated cheese
- Adds rich cheese flavor and body as it melts into the hot base.
- Beaten egg
- Adds richness and body; it thickens gently when stirred into the warm soup.
The step that matters
Stir in the beaten egg off the heat. Egg proteins set at high heat and can curdle or scramble. Removing the pan from the heat before adding the egg lets it blend smoothly and thicken gently.
“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.
