Ingredients
  

For the Crostini:
  • 1 baguette sliced into ¼-inch rounds (~15 slices)
  • 2 tbsp olive oil
  • Pinch of flaky salt
For the Blackberry-Thyme Jam:
  • 1 cup fresh or frozen blackberries
  • 2 tbsp honey or maple syrup
  • ½ tbsp balsamic vinegar
  • 2 tsp fresh thyme leaves
  • Pinch of salt
For the Duck:
  • 1 duck breast skin on
  • Salt and black pepper
To Finish:
  • 4 oz Brie sliced into thin slices (remove rind if preferred)
  • Fresh thyme sprigs or microgreens optional
  • Flaky sea salt for sprinkling

Method
 

Make the Crostini:
  1. Preheat oven to 375°F (190°C). Arrange baguette slices on a baking sheet, brush with olive oil, and sprinkle with flaky salt. Bake for 8–10 minutes, or until golden and crisp. Let cool.
Prepare the Blackberry-Thyme Jam:
  1. In a small saucepan, combine blackberries, honey (or maple syrup), balsamic vinegar, thyme, and a pinch of salt. Simmer on medium heat for 10–15 minutes, stirring and gently mashing the berries until the mixture becomes thick and jammy. Let cool completely.
Sear the Duck Breast:
  1. Score the duck skin in a crosshatch pattern, being careful not to cut into the meat. Season both sides generously with salt and pepper.
  2. Place the duck skin-side down in a cold skillet. Turn heat to medium and cook for 6–8 minutes, letting the fat render and the skin become crisp and golden. Flip and cook for another 5–6 minutes until medium-rare to medium.
  3. Transfer to a cutting board and let rest for 5–10 minutes. Slice thinly against the grain.
Assemble the Crostini:
  1. Place a slice of brie on each crostini. Torch or broil if you’d like to melt the cheese slightly.
  2. Top with a thin slice of duck breast, then spoon a small dollop of blackberry-thyme jam over each. Garnish with microgreens or thyme, and finish with a pinch of flaky salt.
