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.

  3. Spread your chosen jam evenly over the pastry.

  4. Cover with another thin layer of pastry and press the edges together.

  5. Score the surface with a knife to mark cutting lines.

Bake and finish

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

  2. A few minutes before done, remove from oven, brush with egg white, and sprinkle with sugar.

  3. Return to the oven to finish baking and color.

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

  5. Serve with flavored whipped cream 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 up and crisp when baked.
Jam
Adds sweetness and fruity moisture that softens slightly as it heats inside the pastry.
Egg white
Brushed on top, it promotes browning and a glossy, crisp surface.
Sugar
Sprinkled on top, it caramelizes during baking for sweetness and added color.

The step that matters

Brushing with egg white and sugar at the right time. Applied too early, the sugar can burn and the egg white can over-brown before the pastry is cooked through. Applying it a few minutes before the end lets the top set, brown and caramelize evenly while the layers finish baking and puffing.

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.
