Double-Baked Orange Blossom Bostock

Double-Baked Orange Blossom Bostock

Bostock is the pastry chef’s ultimate flex: it looks like three days of lamination, but it’s just stale brioche living its best second life. We soak thick-cut bread in a quick orange-blossom syrup, bury it under a rapid one-bowl frangipane, and bake it until the edges shatter. Café-level breakfast, zero dough-folding required.

Ingredients

  • 1/3 cup water(For the syrup)
  • 1/2 cup granulated sugar(Divided (1/4 cup for syrup, 1/4 cup for frangipane))
  • 1 orange(Zested)
  • 1 tsp orange blossom water(Can substitute with vanilla extract)
  • 4 tbsp cultured butter(Softened to room temperature)
  • 1 large egg(Room temperature)
  • 1/2 cup almond flour(Finely ground)
  • 1/4 tsp kosher salt(Diamond Crystal)
  • 1/2 tsp almond extract
  • 4 thick-cut slices day-old brioche(Cut at least 1-inch thick, left out overnight to dry)
  • 1/2 cup sliced almonds
  • 1 tbsp powdered sugar(For dusting)
  • 1 orange zest of 1 orange(zest)

Instructions

  1. 1

    Preheat oven to 375°F (190°C). In a small saucepan, combine 1/3 cup water, 1/4 cup granulated sugar, and the zest of 1 orange. Bring to a simmer over medium heat until the sugar completely dissolves. Pull it off the heat and stir in 1 tsp orange blossom water. Let it cool slightly.

    5 min

    Tip: If you don't have orange blossom water, vanilla extract or a splash of Grand Marnier works brilliantly. The goal is an aromatic soaking liquid.

  2. 2

    While the syrup cools, build the quick frangipane. In a medium bowl, aggressively mash 4 tbsp cultured butter and the remaining 1/4 cup granulated sugar with a flexible spatula until it forms a thick paste. Vigorously beat in 1 large egg, 1/2 cup almond flour, 1/4 tsp kosher salt, and 1/2 tsp almond extract. You want a smooth, spreadable cream. No stand mixer needed—we're not suffering for brunch.

    5 min

    Tip: If your butter is too cold, the mixture will separate. Just power through and keep mixing; the almond flour will eventually bind it.

  3. 3

    Arrange your 4 thick-cut slices day-old brioche on a parchment-lined sheet pan. Generously brush the tops with the warm orange blossom syrup. Don’t be shy—the bread should drink it up like a sponge. This double-baking technique is exactly why we use stale bread; a fresh slice would just turn to mush.

    2 min

    Tip: Make sure to brush the syrup all the way to the crusts so they don't burn during the second bake.

  4. 4

    Smear the frangipane evenly over the soaked brioche slices, taking it right to the edges to seal in the moisture. Press 1/2 cup sliced almonds firmly into the frangipane layer so they anchor during the bake.

    3 min

    Tip: Going edge-to-edge with the frangipane protects the brioche from scorching and creates a beautiful crust-to-crumb ratio.

  5. 5

    Bake for 15 to 18 minutes. You are looking for the frangipane to puff up and turn a deep, confident golden brown, while the almonds toast to a crisp finish.

    15 min

    Tip: Watch the almonds around the 12-minute mark. If they are browning too aggressively, tent loosely with foil.

  6. 6

    Let the bostock cool on the pan for 5 minutes. The center will settle into a warm, custardy dream while the edges shatter. Dust lightly with 1 tbsp powdered sugar and serve immediately.

    5 min

    Tip: Do not skip the resting time. The frangipane needs a few minutes to set up so it doesn't run when you bite into it.

Chef's Notes

Cami’s shortcut note: The frangipane can sit in an airtight container in the fridge for up to a week. Make it on a Sunday, and you're literally three minutes of prep away from a hot café-level pastry on a Wednesday morning. Butter is not a garnish here—use the cultured stuff for that necessary tang to offset the sweet almond. Don't skip the stale bread step; we need that structure to carry the syrup without collapsing.
