Lightly salt and pepper both sides of the duck breasts. Seal them with freshly minced garlic, freshly smashed ginger, rosemary, thyme, apple slices, and chardonnay wine in a vacuum-sealed sous vide bag.
Sous vide the sealed duck breasts at 105 F for 2 hours.
While the duck cooks, make the sushi rice according to the instructions on the packaging. Make sure not to undercook the sushi rice.
Make the ginger-wasabi drizzle. Blend wasabi paste, ginger, and ginger liquids thoroughly. If the texture is too pasty, add a bit more liquid from the pink ginger jar. Set the drizzle aside until you are ready to serve.
Before removing the duck breasts from the sous vide, heat a thin layer of peanut oil in a skillet to 500 F. Upon opening the sealed duck breasts, pat the breasts dry. Then sear them skin-side-down for one minute, flip, and sear for one more minute on the other side.Tip: It helps to add a grill weight atop the breasts when searing. Duck breasts tend to plump up and not fully contact the heat surface. Pull breasts from the skillet and lightly tent them with aluminum foil. Allow them to rest for 5 minutes before carving.
Make the sushi. It may help to lightly oil your hands. You want to form ovals of sushi rice approximately the size of a 2 ⅔-inch shotshell but a little thicker than a 12-gauge’s circumference. Set them on a plate.
Carve the duck breasts thinly and diagonally and place the slices atop the formed sushi rice. Serve immediately with ginger-wasabi drizzle on the side. You can also put out soy sauce for dipping. Coarse sea salt adds a nice crunch and enhances flavor when lightly sprinkled over the cut duck. Sliced scallions and toasted sesame seeds are also great optional garnishes.
