Ingredients
Directions
The book says “a rather quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Beat the eggs, reserving a little for glazing.
Stir the butter, cheese, and seasoning into the beaten eggs.
Roll out the puff pastry very thin.
Assemble and bake
Spread the cheese mixture over half of the pastry.
Cover with the other half of the pastry and cut into squares.
Glaze the tops with the reserved egg.
Bake for about 10 minutes, until the pastry is done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Parmesan cheese
- Provides savoury, salty flavour and helps the filling set as it bakes.
- Eggs
- Bind the filling and set it, while the reserved egg gives the pastry a glossy, browned top.
- Butter
- Adds richness and flavour and keeps the filling tender.
- Puff pastry
- Forms the flaky, layered case that puffs and crisps in the oven.
The step that matters
Rolling the puff pastry very thin. Thin pastry bakes up crisp and flaky; thick pastry stays doughy underneath and can be undercooked before the filling is set.
