Duchess Loaves

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 the loaves

  1. Preheat the oven to 400°F (200°C).

  2. Roll out small pieces of pastry dough, about the size of a pigeon's egg, into finger shapes.

  3. Place the shaped dough on a buttered baking sheet.

  4. Brush the tops with beaten egg.

Bake and finish

  1. Bake until light golden in color.

  2. Sprinkle finely sifted sugar over the loaves just before they are done.

  3. Return to the oven until the sugar nearly melts.

  4. Use a salamander or broiler to give a glossy finish.

  5. Remove from the oven and let cool.

Fill and serve

  1. Make an incision down the sides and fill with apricot jam.

  2. Serve in a pyramidal form on a napkin.

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

What each ingredient does

Pastry dough
Forms the flaky, golden shell that holds the filling.
Egg
Egg wash browns the surface and gives a glossy sheen.
Sugar
Caramelizes under heat to add sweetness and a glossy finish.
Apricot jam
Adds fruity sweetness and moisture to the filling.

The step that matters

Sugar and finishing under heat. Sugar melts and caramelizes quickly at high heat, so it can scorch or burn if left too long. Watch closely and pull the loaves once the sugar has just melted to keep a glossy, golden finish.

Swap the apricot

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

  1. Raisinfits better
  2. Vanillafits better
  3. Figfits better
  4. Apricotthe original

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