For the Duck

Preheat the water bath to 131°F (55°C).

Sprinkle the duck breasts with the Chinese 5-spice powder then salt and pepper them. Add the duck to the sous vide bags. Seal the bags then place in the water bath and cook for 2 to 4 hours. For more information on the cooking times you can read my detailed article which addresses why is there a range in sous vide cooking times.

For the Vinaigrette

Combine the cider vinegar, honey and cherries in a blender and processes until smooth. Slowly drizzle in the olive oil while blending. Salt and pepper to taste.

To Assemble

Remove the cooked duck from the sous vide bag and pat dry. Lightly salt the duck breast then quickly sear it until the outside has browned and the fat has begun to render. Cut the duck into slices.

Place the mixed greens in a bowl and add the slices of duck. Top with the cherries, walnuts, and tomatoes then drizzle with the vinaigrette.
