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 macaroni with enough plain white sauce to create a thick mixture.
Add the grated cheese, herbs, and seasoning; stir until the cheese is melted.
Bring the sauce to a boil before adding the macaroni, then reduce heat.
Beat the egg yolk and stir it in gradually; keep the pan near the heat without boiling.
Squeeze in lemon juice to taste.
Serve
Serve on a round of toast or fried bread, with cooked vegetables or eggs as desired.

Egg and lemon barely smell alike, yet cooks put them together in 44,316 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
- Macaroni
- Adds bulk and a tender-chewy bite that holds the thick sauce.
- Plain white sauce
- Provides the creamy base and moisture that coats the pasta.
- Grated cheese
- Adds savoury richness and melts into the sauce for body.
- Raw egg yolk
- Enriches and thickens the sauce as its proteins gently set with heat.
- Lemon juice
- Adds acidity that brightens the rich, creamy flavours.
The step that matters
Adding the egg yolk without boiling. Egg yolk proteins set when heated, so if the sauce boils after the yolk goes in, it can curdle and turn grainy. Stirring the yolk in gradually and keeping the pan hot but below boiling keeps the sauce smooth and thick.
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.
