Brown Butter & Sweet Cherry Sourdough Bostock
Bostock is the ultimate café cheat code—a brilliant French baker's trick for transforming yesterday's bread into today's almond-crusted triumph. We’re taking thick slices of day-old sourdough, soaking them in a sharp citrus syrup, and spackling them heavily with brown butter frangipane. Push fresh sweet cherries right into the cream before it hits the oven; they’ll blister and bleed their dark juices into the lacy crumb beneath.

Timeline
Ingredients
- 4 slices Thick-cut day-old brioche or soft sourdough(At least 1-inch thick, slightly stale is best)
- 1/3 cup Water
- 1/4 cup Granulated sugar
- 1 tsp Orange zest(Freshly grated)
- 4 tbsp Cultured butter(Browned and cooled to a soft solid at room temperature)
- 1/4 cup Toasted sugar or light brown sugar
- 1 large Egg(Room temperature)
- 1/2 cup Almond flour(Fine grind)
- 1/2 tsp Flaky sea salt
- 1 cup Sweet cherries(Pitted and halved)
- 1/4 cup Sliced almonds
- 1 sheet parchment paper(for lining baking sheet)
Instructions
- 1
Preheat your oven to 375°F. Line a heavy baking sheet with parchment paper. You want a hot, aggressive oven so the frangipane puffs immediately rather than melting into a puddle.
10 min
Tip: Don't rush the preheat. The initial blast of heat is what sets the crust.
- 2
Make the simple syrup. In a small saucepan, combine 1/3 cup water, 1/4 cup granulated sugar, and 1 tsp orange zest. Simmer over medium heat for 2-3 minutes, just until the sugar completely dissolves. Pull it off the heat and let the citrus oils infuse while you work.
5 min
Tip: If you have a splash of amaretto or kirsch, now is the time to add it to the syrup off-heat.
- 3
Whip the frangipane. In a medium bowl, vigorously mix 4 tbsp cultured butter (browned and cooled) with 1/4 cup toasted sugar or light brown sugar until creamy. Beat in 1 large egg until fully emulsified, then fold in 1/2 cup almond flour and 1/2 tsp flaky sea salt. It should look like thick, grainy buttercream.
5 min
Tip: The brown butter gives incredible depth, but it must be cooled to room temp before mixing, or your frangipane will split.
- 4
Prep the fruit. Pit and halve 1 cup sweet cherries. Work quickly but carefully. We want distinct halves that will cup the almond cream as they roast.
5 min
Tip: Do not skip pitting them manually; nobody wants a dental emergency at brunch.
- 5
Arrange the 4 slices thick-cut day-old brioche or soft sourdough on your prepared sheet pan. Using a pastry brush, generously dab the warm orange syrup over the bread, going right to the edges. The crumb should be saturated but not falling apart tight like a bad alibi.
2 min
Tip: Don't be shy with the syrup. A dry bostock is a tragedy.
- 6
Spackle each soaked slice with a thick, even layer of the frangipane, spreading edge to edge to seal in the moisture. Press the halved cherries firmly into the almond cream, then scatter 1/4 cup sliced almonds over the open spaces.
3 min
Tip: Pushing the cherries down prevents them from rolling off when the frangipane puffs up.
- 7
Bake for 18 to 22 minutes. You are looking for strict visual cues: the frangipane should be puffed, deeply golden brown, and just slightly wobbly in the dead center, while the cherries slump and release their juices. Let time do the work.
20 min
Tip: Cool for at least 10 minutes on the pan before eating. Frangipane needs a moment to set, otherwise it will taste raw.
Chef's Notes
Cami's shortcut note: Brown the butter the night before and leave it covered on the counter. It will be the perfect pliable texture by morning. Don't skip the citrus syrup soak; without it, you're just eating toast with almond paste. Butter is not a garnish, and we're not suffering for brunch.
