Lightly salt and pepper the duck breasts. Seal the breasts, garlic, fresh herbs, apple slices, anise stars, and white wine into a vacuum-sealed bag. Cook in the sous vide bath at 105 degrees for 2 hours.
After one hour has passed, start the sauce. Heat a skillet on medium-low. Add the salted butter. Once it has melted, add the sliced shallots. Lightly salt and pepper.
Stir the shallots, cooking until they’re slightly seared and soft. Add the freshly minced garlic and ginger and stir for 5 more minutes. Deglaze the pan with the sparkling wine. Simmer for 5 minutes.
Add raspberry preserves, chicken stock, port wine, chili crips, and orange zest. Turn the heat to low and allow it to reduce until it’s thick and sticky. Once there, turn off heat. Rinse fresh whole raspberries and add them to the skillet with the sauce.
After 2 hours in the sous-vide bath at 105 F, pre-heat a skillet or grill to a piping-hot 600 to 700 degrees F. Remove the vacuum sealed bag and cut it open. Thoroughly pat-dry the duck breasts until dry; dry meat makes for a better sear.
Once dry, add the duck breasts skin-side down to the piping-hot skillet or grill, sear for 1 minute, then flip. Sear for 1 more minute, then remove them from the grill, lightly drizzle them with olive oil, and loosely tent them with aluminum foil.
Allow the duck breasts to rest for 10 minutes. To serve, add sauce to the bottom of the dish and add the sliced duck on top. Top the duck with a bit of coarse sea salt and fresh basil. Enjoy!
