Brown the duck
18 minPat the duck legs dry and rub them with salt, black pepper, and cumin. Heat a wide, heavy-bottomed pot without oil. Place the legs skin-side down and cook over low to medium heat for 12 minutes, until the skin is golden brown and has rendered its fat. Turn and brown for 5 minutes more, then transfer to a plate. Leave 3 tablespoons of the fat in the pot and discard the rest.
