Why it works: Cheese and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 7,962 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Cheese Sandwiches
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 the filling
Melt the butter in a pan.
Add the cheese, beaten egg, egg yolk, mustard, salt, pepper, and cayenne to the melted butter and mix well.
Assemble and bake
Roll out the pastry thinly and lay it on a baking sheet.
Spread the cheese mixture over half of the pastry and fold the other half over it.
Pinch the edges to seal and lightly mark the top into finger lengths.
Bake in a 400°F (200°C) oven until golden.
Cut into fingers and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pastry
- Forms the crisp, flaky outer layers that puff and brown in the oven.
- Parmesan or dry grated cheese
- Adds savoury flavour and sets firmly with the egg as it bakes.
- Egg and egg yolk
- Binds the cheese filling and helps it set into a firm, sliceable custard.
- Butter
- Adds richness and carries the flavour of the seasonings through the filling.
- Mustard
- Adds sharp, tangy flavour that balances the richness of the cheese and butter.
The step that matters
Pinch the edges to seal. A tight seal keeps the cheese filling from leaking out during baking, so the pastry stays filled and cooks evenly.
Swap the mustard
How well each one fits the dish's main ingredients (cheese, egg, pepper, butter):

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