Why it works: Cheese and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,130 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
Make the sauce
In a saucepan, combine the cooked pipe macaroni with enough plain white sauce to create a thick mixture.
Add the grated cheese, herbs, and seasoning, and stir until the cheese is dissolved.
Bring the sauce to a boil, then reduce heat.
Once the right consistency is reached, beat in the raw egg yolk gradually, keeping the pan near the heat without boiling.
Squeeze in a little lemon juice.
Serve
Serve on a round of toast or fried bread, garnished with cooked vegetables or slices of toast.

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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked pipe macaroni
- Provides the bulk and body of the dish, holding the sauce together.
- Grated cheese
- Melts into the sauce to add richness and savoury flavour.
- Raw egg yolk
- Thickens the sauce gently as it heats, giving it a smooth, creamy texture.
- Plain white sauce
- Forms the creamy base that coats the macaroni.
The step that matters
Adding the raw egg yolk. Egg yolk thickens through gentle heat. If the sauce boils or the yolk is added too quickly, it can scramble and turn grainy instead of smooth and creamy.
Swap the lemon
How well each one fits the dish's main ingredients (sauce, cheese, egg, bread):

Fit is the average pairing score against sauce, cheese, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
