1. To make the confit, combine the shallots, honey, and ginger in a saucepan. Cook over medium heat, stirring often, until the shallots are pale.

2. Stir in the vinegar and bring to a boil. Reduce the heat to medium-low and simmer for about 8 minutes, or until the liquid is syrupy. Stir in 2/3 cup of water and simmer for about 8 minutes more, or until the mixture is golden and thickened, but not runny.

3. Meanwhile, preheat the oven to 400°F (200°C). Score the duck skin in a crosshatch pattern. Heat a large frying pan over medium-high heat. In batches, add the duck breasts, skin side down, and cook about 4 minutes, until the skin is browned, pouring off the fat as needed. Turn and cook the other side 2 minutes, until browned. Transfer to a roasting pan, skin side up. Brush with honey, sprinkle with the five-spice powder and salt and pepper. Bake for about 8 minutes, or until the duck breasts are medium-rare when pierced in the center.

4. Transfer to a carving board and let stand for 5 minutes. Carve on the diagonal into thick slices, transfer to dinner plates, and serve with the confit.
