Pastry Sandwiches

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Roll out the puff pastry thinly.

  2. Place half of the pastry on a baking sheet and spread the jam evenly over it.

  3. Cover the jam with another thin layer of pastry, pressing the edges together.

  4. Mark the surface with a knife to indicate where to cut after baking.

Bake and finish

  1. Bake at 400°F (200°C) for 20 to 30 minutes.

  2. Before finishing, remove from the oven and brush the top with the egg white.

  3. Sprinkle sifted sugar over the egg wash and return to the oven to color.

  4. Once cooled, cut into 2-inch strips and arrange them in a pyramid shape on a dish.

  5. Serve with flavored whipped cream poured in the center.

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

What each ingredient does

Puff pastry
Forms flaky, layered sandwich walls that puff and separate when baked.
Jam
Adds sweetness and fruit flavor and moisture between the pastry layers.
Egg white
Forms a glossy wash that helps the top brown and the sugar caramelize.
Sifted sugar
Caramelizes on the egg wash to give the top a sweet, browned finish.

The step that matters

Pressing the edges together. If the edges are not sealed, the jam can leak out during baking and the pastry may not puff evenly around the filling.

Swap the apricot

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

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