Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare
Grate enough old cheese to cover the prepared toast.
Make the cheese mixture
Combine cheese, butter, and milk in a saucepan over low heat, stirring until smooth.
Bake and serve
Spread the cheese mixture over the toast.
For a richer version, add mustard, cayenne, and egg yolks to the cheese mixture before spreading it on the toast.
Set the toast in the oven to melt the cheese.
Bake in a hot oven (400°F) for 4 minutes.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Old cheese
- Melts into the sauce and gives the toast its main flavour and body.
- Butter
- Adds fat that makes the cheese mixture smooth and rich.
- Milk
- Loosens the cheese so it blends into a smooth, spreadable mixture.
The step that matters
Stirring the cheese mixture over low heat until smooth. Cheese proteins tighten and turn grainy or oily when overheated, so gentle low heat and steady stirring keep the sauce smooth.
Swap the mustard
How well each one fits the dish's main ingredients (cheese, butter, milk, pepper, bread):
- Potatofits better
- Capsicumfits better
- Tomatofits better
- Mustardthe original
Fit is the average pairing score against cheese, butter, milk, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
