Why it works: Apricot and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 3,630 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Pastry Sandwiches
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Divide the puff pastry in half and roll each half into a square as thin as possible.
Place one half on a buttered baking sheet and spread it lightly with jam.
Cover with the second half, pressing the edges together with a rolling pin.
If using the second method, moisten the edges with water or beaten egg before sealing.
Bake and serve
Mark the pastry into divisions and bake in a preheated oven at 350°F (175°C) for 15 to 20 minutes.
Brush the top with water and sprinkle with sifted sugar.
Cut into pieces while still hot along the marked divisions.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Puff pastry
- Its layers puff and crisp in the oven, giving the sandwich a flaky texture.
- Apricot or peach jam
- Adds sweetness and fruity moisture that fills the pastry between the layers.
- Beaten egg
- Can seal the edges and promote browning on the pastry surface.
The step that matters
Sealing the edges. If the edges are not pressed firmly together, the jam can leak out during baking and the pastry may not puff evenly. Moistening the edges helps them bond.
Swap the apricot
How well each one fits the dish's main ingredients (egg, sugar):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Apricotthe original
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
