Why it works: Vanilla and sugar are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Vanilla Custard Slices
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 pastry
Roll the pastry into two long strips, each 2 inches wide.
Bake in a 400°F (200°C) oven for 12 minutes.
Remove from the oven and spread thick custard on one strip.
Assemble and finish
Flavor the custard with vanilla essence and sweeten with sugar.
Place the second strip of pastry on top.
Ice with clear icing, cut into sandwiches, and serve.

Shared aroma: beta-damascenone (apple, rose).
Vanilla and sugar barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Puff pastry
- Bakes into flaky, layered strips that give the sandwich its crisp structure.
- Thick custard
- Provides a soft, creamy filling that contrasts with the crisp pastry.
- Sugar
- Adds sweetness to the custard and balances the richness of the filling.
- Vanilla essence
- Adds aromatic flavor to the custard filling.
The step that matters
Baking the pastry strip. Puff pastry rises through steam released from its layers of fat and water. Baking it fully at the stated heat sets and crisps the layers so they stay flaky rather than soggy under the custard.
