A Vol-au-vent of Fruit

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the pastry

  1. Preheat the oven to 350°F (175°C).

  2. Mix flour, butter, salt, egg yolk, and water to form a dough.

  3. Roll out the dough and cut into a large circle for the base.

  4. Cut a smaller circle for the top and mark it with a fluted cutter.

  5. Bake the crust for 20 to 30 minutes until golden.

Make the fruit filling

  1. Stew the fruit in syrup until tender, then keep warm.

  2. Boil the syrup rapidly until it thickens to a jelly-like consistency.

Assemble

  1. Fill the baked crust with the fruit and pour the syrup over it.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: isobutyraldehyde (malty, green).

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

All-purpose flour
Forms the dough's structure once mixed with liquid and fat.
Butter
Adds fat that makes the pastry tender and flaky as it bakes.
Egg yolk
Adds richness and helps bind the dough and brown the crust.
Sugar
Adds sweetness and helps the syrup thicken and set as it reduces.
Syrup
Cooks with the fruit and thickens into a glossy, jelly-like coating.
Peaches
Provide the main fruit flavour and soften into a tender filling when stewed.

The step that matters

Boil the syrup rapidly until it thickens. Syrup that is not reduced enough stays thin and runs out of the crust. Rapid boiling evaporates water and concentrates the sugar so it sets to a jelly-like consistency as it cools.

Swap the plum

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

  1. Vanillafits better
  2. Figfits about as well
  3. Pearfits about as well
  4. Plumthe original

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