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
Heat the milk with the mace, then remove the mace.
In a separate bowl, rub the butter and flour together, then wet with a little cold milk.
Add the butter and flour mixture to the hot milk along with pepper and salt.
When cooked, beat the egg yolks lightly and add them along with the cheese.
Cook for 1 minute longer before serving.

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
- Flour
- Thickens the milk into a smooth, creamy soup when cooked with the butter.
- Egg yolks
- Enrich the soup and add body and richness when stirred in at the end.
- Cheese
- Adds savory flavor and richness to the soup.
- Butter
- Adds richness and flavor, and coats the flour so it blends smoothly.
The step that matters
Adding the egg yolks. Egg yolks can scramble if they meet very hot liquid directly. Beating them lightly and adding them after the soup is cooked, then cooking only briefly, helps keep the soup smooth and creamy.
Swap the mace
How well each one fits the dish's main ingredients (milk, flour, egg, butter, cheese, pepper):
- Nutmegfits better
- Parsleyfits better
- Cinnamonfits better
- Macethe original
Fit is the average pairing score against milk, flour, egg, butter, cheese, pepper. Candidates are from the same food group and used in at least 100 recipes.
