Why it works: Peach and sugar are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 2,308 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Pastry Sandwiches

Oven, in the book's wordsA moderate oven

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

  1. Divide the puff pastry in half and roll each half into a square as thin as possible.

  2. Place one half on a buttered baking sheet and spread it lightly with jam.

Assemble and bake

  1. Cover with the second half, pressing the edges together with a rolling pin.

  2. Mark the pastry into divisions and bake in a preheated oven at 350°F (175°C) for 15 to 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Puff pastry
Its layers of fat and dough puff with steam to create a flaky, airy texture.
Peach or apricot jam
Provides sweetness and fruity flavor, and moisture that softens the pastry layers around it.
Beaten egg
Seals the edges and promotes browning on the pastry surface.

The step that matters

Rolling the pastry as thin as possible. Thin dough lets the layers of fat and dough separate and puff properly in the oven. Thick pastry bakes dense and doughy rather than flaky.

Swap the peach

How well each one fits the dish's main ingredients (egg, sugar):

  1. Vanillafits better
  2. Raisinfits better
  3. Lemonfits better
  4. Peachthe original

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