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 ↓
Macaroni Cheese
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash the macaroni and boil it in plenty of salted water for 30 minutes.
Assemble and bake
Layer the macaroni and cheese alternately in a dish, with cheese on top.
Fill the dish with milk and add a little butter.
Bake in a hot oven at 400°F (200°C) for 30 minutes.
If desired, add pieces of butter and a sprinkling of mustard, salt, and pepper between layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk and body of the dish, holding the sauce between its layers.
- Cheese
- Melts into the milk to create a rich, creamy sauce with savoury flavour.
- Milk
- Provides moisture and, as it bakes, its proteins set into a creamy sauce.
- Butter
- Adds fat for richness and helps the top brown lightly in the oven.
The step that matters
Bake at 400°F (200°C). Milk proteins set gently into a creamy sauce as the dish heats. Too much heat or time can make the sauce dry, grainy, or separated, so check the dish as it bakes.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (cheese, milk, butter, pepper):
- Potatofits better
- Capsicumfits better
- Tomatofits better
- Mustardthe original
Fit is the average pairing score against cheese, milk, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
