Set up your grill for moderate to high heat over embers and for close proximity grilling.
Slice the duck breast across its width into 1-cm slices. Thread through the widest parts onto the skewers, ensuring you pierce the skin at both ends to secure. Season once all the duck is on the skewers.
Stir the honey and sriracha together in a small bowl.
Grill the duck skewers for a few minutes on each side until brown, then brush on the spicy sweet glaze using a silicone pastry brush and grill for 1–2 minutes per side until the glaze is seared in. Make sure the internal temperature has reached 74°C on a digital probe thermometer.
Enjoy with a side of rice if you like, and a cold beer.
