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 pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 of the soup and the sauce.
- Flour
- Thickens the sauce so the soup has body.
- Egg yolks
- Enriches the soup and thickens it gently when cooked.
- Grated cheese
- Adds rich savoury flavour and melts into the soup.
- Butter
- Adds fat and richness to the sauce.
The step that matters
Adding the egg yolks. Egg yolks thicken by coagulating when heated. If the sauce is too hot when they go in, or they are cooked too long, they can scramble and turn grainy. Add them once the sauce is cooked and cook gently.
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.
