Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Cheese Toast
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make and top the toast
In a bowl, mix the grated cheese, butter, mustard, cream, egg yolk, cayenne, and salt until well combined.
Pour the mixture over the slice of toast.
Bake and serve
Bake in the oven until browned and bubbly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grated cheese
- Melts and browns on top, providing the main flavor and rich texture.
- Butter
- Adds fat that keeps the topping smooth and helps it brown.
- Egg yolk
- Emulsifies with the fat and sets during baking, giving the topping body.
- Cream
- Adds moisture so the mixture spreads easily and stays creamy when baked.
- Mustard
- Adds sharpness that balances the richness of the cheese and fat.
The step that matters
Bake until browned and bubbly. Underbaking leaves the egg yolk and cream unset and the topping pale, while overbaking can dry and toughen the cheese. Watch for a bubbling surface with golden-brown spots.
Swap the mustard

Fit is the average pairing score against cheese, butter, cream, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
