A Vol-au-vent Op 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 crust

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

  2. Make the crust by mixing flour, butter, salt, egg yolk, and enough water to form a dough.

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

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

Prepare the fruit and syrup

  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 and serve

  1. Fill the baked crust with the warm 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 structure of the dough once combined with water and fat.
Butter
Adds fat that makes the crust tender and flaky as it bakes.
Egg yolk
Enriches the dough, adding richness and helping it bind and brown.
Syrup
Sweetens the fruit and, when boiled down, thickens into a jelly-like glaze.
Peaches
Provide the soft, juicy fruit filling that gives moisture and sweetness.

The step that matters

Boil the syrup rapidly until it thickens. Syrup thickens as water evaporates and sugar concentrates. If it is under-boiled it stays runny and soaks the crust; if over-boiled it can turn too stiff or caramelise. Watching for a jelly-like consistency sets the glaze properly.

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.
