In a bowl, mix the salt with the crushed peppercorns, garlic, bay leaves, and the thyme. Put the duck legs in a large, shallow container and sprinkle them all over with the salt mixture. Cover and refrigerate for 24 hours.
Fill and preheat the sous-vide machine to 167°F.
Rinse the legs and dry them thoroughly with paper towels. Package the legs in pairs and add 3 to 4 tablespoons of duck fat per pouch. Using a vacuum sealer, seal the bags on high.
Place the pouches in the water bath and cook for 10 hours.
Cool rapidly the pouches in ice water and refrigerate until ready to use.
In a heavy-bottomed skillet, crisp up the duck confit on the skin side.
Place in a 375°F oven until heated through.
Serve with the pomegranate poached pear and mache salad.

For the Mache (Corn) Salad
Toss the mache salad with sherry vinegar and olive oil, to taste. Season with salt and pepper. Add the toasted walnuts, shaved pecorino, and pomegranate. Serve with the crispy duck confit.
