Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the dish and gives it its chewy, starchy body.
- Milk
- Forms the liquid base of the cream sauce and adds richness and softness.
- Butter
- Adds fat for richer flavour and a smoother mouthfeel in the sauce and macaroni.
- Egg
- Thickens the hot sauce as its proteins set, giving it a creamy consistency.
The step that matters
Adding the beaten egg to the hot sauce. Egg proteins set when heated, so if the sauce is too hot or boiling when the egg goes in, it can curdle or turn grainy. Stir steadily and keep the heat moderate so it thickens smoothly.
Swap the white pepper
How well each one fits the dish's main ingredients (milk, butter, cheese, egg):
- Nutmegfits better
- Cinnamonfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against milk, butter, cheese, egg. Candidates are from the same food group and used in at least 100 recipes.
