Why it works: Bread and butter 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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cut the stale loaf of bread into slices ¼ inch thick.
Divide the slices into pieces 2 inches long and 1 inch wide.
Fry and top
Fry the pieces in hot butter or oil until golden brown.
Spread a thin layer of mustard on each piece.
Top with cheese and place in a 400°F (200°C) oven until the cheese is melted.
Serve
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Its dry crumb crisps when fried and holds the toppings without going soggy.
- Butter or oil
- Frying in hot fat browns the bread surface and adds rich flavour.
- Mustard
- Adds sharp acidity and pungency that cut through the richness of the cheese.
- Cheese
- Melts in the oven to form a savoury, binding topping over the bread.
The step that matters
Frying the bread until golden brown. Fat must be hot enough to brown the surface quickly. If the pieces fry slowly they absorb excess oil and turn greasy and soft, so the base loses its crispness before the cheese is added.
Swap the mustard
How well each one fits the dish's main ingredients (bread, butter, cheese):
- Tomatofits better
- Potatofits about as well
- Onionfits about as well
- Mustardthe original
Fit is the average pairing score against bread, butter, cheese. Candidates are from the same food group and used in at least 100 recipes.
