Ingredients:
- 2 skin on duck breasts (approx. 7 oz / 200g each)
- 5g Diamond Crystal Kosher Salt
- 2g freshly cracked black pepper
- 2 sprigs fresh thyme
- 1 clove garlic, smashed
- 5ml neutral oil
- 1 pinch flaky sea salt
Instructions:
- Score the duck skin in a tight diamond pattern, ensuring you cut through the fat but do not pierce the meat. Season both sides aggressively with kosher salt and black pepper.
- Set your immersion circulator to 131°F (55°C) for medium-rare or 135°F (57°C) for medium.
- Place the seasoned duck breasts into a vacuum-seal bag or heavy-duty freezer bag along with the thyme sprigs and smashed garlic. Seal using a vacuum sealer or the water displacement method.
- Submerge the bag in the water bath and cook for 2 hours.
- Remove the duck from the bag and pat the skin extremely dry with paper towels. Discard the herbs and garlic.
- Place the duck breasts skin-side down in a cold cast iron skillet. Turn the heat to medium-low. Allow the fat to render slowly and the skin to crisp into a deep mahogany brown (approximately 5-8 minutes). Finish with a 30-60 second sear on the flesh side.
- Rest for 5 minutes, then slice and finish with a pinch of flaky sea salt.
